I haven’t seen one. Not in the real world. Only in videos. Until a few weeks ago, I didn’t even know that there was an active RV community around this concept of using a heavy duty truck tractor to tow a fifth wheel.
A typical RV Hauler rig might look like this:
This photo is a screen grab from one of the videos I had reviewed on this part of the RV community.
Here is a video showing a rally of these unique RVs.
The man behind the video? Gregg Shields. He has retired from building RV Haulers but his YouTube channel and his website provides a lot of relevant information especially for Canadians interested in going this route.
It looks as though the cost for a used heavy duty truck tractor is not all that expensive. A complete rig like the one shown in the picture above is similar to the cost of a Class A motorhome. And, in our province of Ontario, if you opt for a single rear axle, you may not need a commercial driver’s license to tow a fifth wheel. You would still require a Z endorsement for the air brakes.
The used heavy duty truck tractor might be a better option than a diesel pickup truck when towing the really large fifth wheel units. Plus, they look pretty cool.
