Lizz, A trailer is an excellent way to camp. Look up “teardrop” trailers up on the web. They are fascinating. This is a similar concept to the Tentrax unit referenced. Trailers work well with small low powered cars, for people who can’t afford, or don’t have space, for a recreational vehicle. My utility trailer is 60 years old and has seen more use than I can recount. It has wheels with 5 X 4.5 bolt circle. This means the wheels and tires fit many Ford and Chrysler products, more or less universal wheels. Thus, there are plenty of spare tires when going off road. If you notice in the Tentrax advertisement pictures, the tires and wheels match the off road tow vehicle, important.
Recently, I towed my utility trailer on the highway to haul something some distance away. Fuel economy was virtually the same as my truck would have gotten empty.
You don’t need to spend 4 or 5 grand for a utility trailer. Little used boat trailers can be bought for a few dollars. Add plywood on the frame, tie on your stuff. Be sure and repack the hubs on a used trailer before going on the highway. Wal-Mart stocks a supply of wheels, hubs, and trailer accessories. Most light truck bumpers are made to mount a trailer ball and stressed for towing up to 2000 pounds. Newer pickups even have ready made holes under the rear bumper for safety chains.
After you get your new FWC/ATC you can continue to use your trailer to haul gear for those nieces and nephews. John
