Your truck should handler nearly any non-park model travel trailer. So pick your size/length based on the floorplan you like compromised with how many sites you want to fit it. A 25' RV fits in a 35' site, but not the opposite. You may want to browse some campgrounds that you think you will like for the number/location of sites that a 35' RV fits. Some "campgrounds" have hundreds of sites for 40+ foot motorhomes. Some campgrounds do not accommodate anything longer than 25'. So find out what type you expect to camp in.
Thats solid advice, something to consider
