Trailer Boss for Sales & Service of Cargo, Dump, Utility, & Other Trailers

Loading & Distribution

Handling and controlling your tow vehicle and trailer will be greatly improved when the cargo is correctly loaded and distributed. Your tow vehicle and trailer owner’s manual are the best resources you have to learn how to:

  • Balance weight from side to side
  • Secure and brace all items to prevent them from moving during travel
  • Adjust the height of the two vehicle/trailer interface
  • Distribute cargo weight evenly along the length of the trailer
  • Apply load leveling (weight distributing hitch bars)

Most trailers and tow vehicles should be parallel to the ground while traveling.

When towing a trailer you need to know what is going on behind you. Sometimes this means that you need to adjust your mirrors so that you can see the end of the trailer plus some of the area to the left and right of each end.  You need to be able to observe what’s going on behind and directly to the side of the rear of the trailer when on the road.

If the trailer you are pulling is long, especially something such as an enclosed trailer which limits your view, you may need to use side mirror extensions and special horizon mirrors to extend the viewing area.

Remember that blind spots are inevitable when towing most enclosed trailers.  You need to be aware of your surroundings and any vehicle which may be pulling up behind you.

One of our larger trailers such as the Pace CargoSport is 8.5 X 24. You will need to adjust your mirrors on this one.

24’/10K Pace CargoSport – A really solid trailer!

This is a really solid trailer that features:

  • 24′ 10K
  • 1-piece aluminum roof
  • front corner wraps
  • fully undercoated, radials
  • LED lighting
  • box tube construction
  • white walls & ceiling
  • 3 year warranty!

At Trailer Boss in Spokane and our other stores we like to make sure our customers understand the best equipment to be used on all their trailers.

Remember passenger cars and light trucks are designed to give the passengers a smooth, comfortable ride. This design extends to the tires of such vehicles. The tires on these vehicles have sidewalls which allow for flexibility. Putting such a tire on a trailer is not a good idea. Trailer tires are designed to accommodate loads and weights, not for a smooth ride. Putting these softer tires on a trailer can cause overheating of the tire and potential blowout problems.

Trailers Sales and Service, Portland, OR to Spokane, WA

Previously we talked about checking your tires for cracks to prevent blows outs as well as inflating them correctly. There are a couple other things you can consider to decrease your risk of having a blowout whether on a cargo trailer, utility trailer, dump trailer or any other trailer.

The Seattle, Spokane, Vancouver, BC, and Portland area all have high and low temperatures. Trailer tires are not immune to the shrinking and welling that outdoor temperatures can cause. As the summer heats up and then nights grow cool there can be cracking with your tires. When temperatures are changing, you need to visually inspect tires to insure they are not cracking.

Just like the trailer, tires have capacity ratings. Overloading a trailer is also overloading your tires. This puts stress on the tires. The pressure within the tire will rise. This causes flexing of the walls of the tire. If there are any small punctures or leaks in the tires, you have a higher risk of blowout. Keep yourself and your trailer safe by monitoring the size of your load.

If you come into Trailer Boss we will insure that you get the proper tire for your trailer. If, however, you have a trailer and want to replace the tires look for the size marking on the side of the old tire. There should be marked indication that they are for trailer use only.

Don’t change the size of the tire. Doing so would require changing the tongue height so the trailer can be kept at the proper angle when loaded. Determine the load range of the original tire and buy your new tire with the same load capacity. You can get this information off the side of the tire.

Be sure to match tire types. For example if the tire on the other side of the trailer are bias ply, replace the tire with a bias ply. If the other tire or tires are radial, you need a replacement tire that is also of radial construction.

If you have any concerns about tires or any other questions regarding the use of your trailer, come into  Trailer Boss. We have skilled technicians and our staff are experts on the topic of towing.

Need your trailer serviced or repaired? Trailer Boss has technicians in all three of our Northwest locations—Olympia, Washington; Rochester, Washington; Everett, Washington.

When pulling a trailer, the last thing you want is to have a tire blowout on either your towing vehicle or your trailer. Blowouts can occur for several reasons.

  • Improper maintenance
  • Roadside hazards
  • Extremes of weather

A puncture or crack in the tire can cause small openings in the tire and increase the risk of a blowout or flattening. Check tires frequently for punctures from nails, screws or other sharp objects.

Know the recommended pounds per square inch (PSI) for your tires and keep the tires inflated to the recommended levels. Don’t use pressure gauges that you might find in service stations. These gauges have been used so frequently they are often very inaccurate.

When a trailer tire is under-filled, highway speeds and temperatures can produce disproportionate heat to build in the tire. This can reduce the seal between the tire wall and the tread. If this continues under high speeds or rising outside temperatures, the tire can separate and cause a blowout.

Always check tire pressure and don’t under or over-inflate your tires.

If you have any questions about any aspect of your trailer, please, feel free to contact Trailer Boss’ full-service, repair facility. We have mechanics on duty to provide the service you need.

We have Cargo Trailers for Vancouver, BC customers as well as Utility Trailers in Seattle as well as Cargo Trailers in Seattle, and Cargo Trailers in Portland. We have a variety of trailers. Come in soon.

When pulling a trailer you need to be aware of the tongue weight (TW) in comparison to the gross trailer weight (GTW).

GTW is the gross total weight of the trailer. The tongue weight is the percentage of the load—typically about 10 to 15 percent of the GTW–which is far enough forward on the trailer that it presses down on the hitch.   TW also includes anything that is loaded on the towing vehicle behind the rear axle.

If the TW is too high for the GTW this can force the hitch of the trailer and the rear axle of the tow vehicle to dive. This means that the front of the trailer will head toward the ground. When this happens the front of the towing vehicle can actually lift off the ground.

If the “dive” is too severe you can lose braking traction and steering control of the wheels on the front axle. This can be dangerous.

If, on the other hand, you have too little TW, a trailer will be more likely to swing back and forth.

At Trailer Boss we want you to know that checking into weight distribution hitches is a good idea. These type of hitches can improve a vehicle’s ability to turn, brake and steer, especially when hauling large loads.

The personnel at Trailer Boss understand the weight equation and are prepared to explain everything you need to know about pulling a trailer.

Come in to one of our three locations. We will get you set up with the safest hitches imaginable.

The roadway is not only a pristine, safe place. Other drivers often drop sharp objects such as a nail or screw. Whenever possible, drive around debris on the road.  These sharp items can cause a flat tire.

It is possible that your trailer will fall victim to one of these sharp objects at least once during your lifetime.

Vandalism is also a possibility. Be sure to regularly check your tire pressure.

At Trailer Boss we are able to supply you with a spare tire for your new trailer.

Just after dark I was driving on a rather crowded freeway when I saw a pickup truck pulling a 22-foot long equipment trailer. The trailer was empty and was hard to see because there were no lights on it. I don’t know if they were connected properly, or why someone would endanger themselves and others on the road by driving around without lights.

I notice trailers. Most everyone who works at Trailer Boss would have noticed it. I was wondering how many other people on the road would see this trailer on a dark night.

On the freeway, doing 65, there was no way to notify the driver of the danger he was pulling.  I actually felt it was my civic duty to stay in the lane right behind the trailer so an unsuspecting driver wouldn’t change lanes or wouldn’t pull up behind it.  For about five miles I followed him. He finally signaled, the lights on the trailer remained dark, took an exit and left the freeway.  I hoped his destination was close.

If you have trouble with your lights, don’t take a chance. Stop buy Trailer Boss in Olympia, Rochester or Everett and our parts and service department will quickly diagnose the problem and get you safely back on the road.

We rent trailers to customers all across the Northwest in Seattle, Olympia, Portland, Vancouver, Everett, Centralia, Tacoma, Spokane, and places in between.

We have buyers for our trailers in all of these locations from Vancouver, BC to Portland, Oregon.

Our parts and service guys want to help you be safe with a rented trailer or one you buy from us or one you already own.

See you soon.
