1st time 5er buyer needs advice

Hi. The only recommendation I have is make sure you stay within the payload rating of the F150. If you have maxtow package. I believe your trucks payload (amount you can safely load on axles) is around 2000 lbs (maybe less). That 2000 lbs includes pin weight, hitch, anything inbed, anything iin cab including passengers, dog, etc. This will limit your choices to an fifth wheel with a (loaded not dry) pin weight of around 1,200 lbs. Please keep in mind that the actual pin weight in fifth wheel rvs is about 20% of the loaded weight of the trailer. This means that the gvwr of the fiver that will be within payload limits will be around 7000 lbs (not dryweight). The term 1/2 towable is used too loosely in the fifth wheel marketing world IMO.
I recommend a 3/4 ton truck minimum for fifth wheel towing.
