A 1ton single rear wheel ought to do the trick. If short bed, you might need a slider hitch.
If you look at '15-up models, lots of them have the hitch mount builtin from the factory.

Not much difference between the 3/4 T and 1 T pickups, except the ability to carry about 1000-1500lbs more of pin weight on the rear axle--keep that in mind as you look them over.

It would be good for you to get knowledgeable (if not already) about the terms:
GVWR--Gross Vehicle Weight Rating, the most the truck or trailer should ever be loaded.
GAWR--Gross Axle Weight Rating, most the axle should have to carry
GCVWR--Gross Combined Vehicle Weight Rating, most the truck/trailer together should weigh.
Payload--most weight the tow vehicle can carry, very important when figuring pin weight of fiver on rear axle
Pin Weight--weight the fiver transfers to the truck/rear axle when towing
Dry Weight--weight of the trailer when it is built, can/will be higher than listed most of the time
Most all of the weights listed by truck and trailer mfgs is the lowest it can weigh before any people and options are added. This figure causes a lot of problems when it is used exclusively to rate tow vehicles and trailers together.
Just read up on several of the RV forums, you'll pick all this up quickly.
Good hunting.
And welcome to the forum.
