What is the Best Truck for Towing a 5th Wheel RV?

Helpful Expert Reply:

You are doing the right thing by doing the research first. There is a lot of conflicting information out there so let me break it down for you and I will provide some part recommendations at the end. Basically, if you want to tow a 5th wheel trailer, the best trucks are going to be long bed 3/4 or 1 tons like a Ford F-250/F-350, Chevy/GMC 2500/3500, or Ram 2500/3500. Half ton trucks could work but are not nearly as capable as the larger trucks.

A long bed for sure is something you will want. Having a long bed means that you will not need a slider hitch, which costs more and requires getting out of the truck to manually slide the hitch back to make tight maneuvers. It also means you will not need a Sidewinder replacement pin box which can also be expensive.

It is less likely that you will need additional suspension enhancement with the larger trucks. I recommend finding one you like that has overload springs for additional support. A dually is not necessary unless that is something you want. Also, look for a truck that has a factory 7-Way trailer connector so it will be easy to add in-bed wiring for your trailer.

The larger trucks are going to have the higher towing capacities as well. While 15K is not the heaviest 5th wheel trailer, it could be too much for a half ton truck. A 3/4 or 1 ton will have the capacity you need.

A diesel engine is a good idea because they are capable of so much towing power and torque. If you get an automatic transmission then make sure the truck has a large transmission cooler or add a supplemental cooler. A lot of trucks do have larger transmission coolers from the factory. But since transmission fluid cannot be overcooled, adding a supplemental cooler is never a bad idea.

The recommendations listed above will give you the right vehicle for the job. The make of truck is a matter of personal preference among most people so if you find one that fits the description above, Ford, Chevy, or Dodge, it will work well for you. I have included a link to an FAQ on 5th wheel trailer hitch information. Below are my part recommendations for each of the big 3 manufacturers:
