New to the RV life

My recommend is to stay at 30 or under so you have access to State and National Park sites.. over 30 and you lose a lot of great campgrounds! With 2 boys, bunk room is a great idea so they have their "own" space and privacy. Get an Ultralight and you will be fine with an F150. I pull a 30 foot Bullet Ultralight with my Expedition and that has less towing capacity than a F150.Mine is a 285RLS and only weighs 6000 loaded, 5400 dry! Hitch is about 600 lbs. No problem with an E2 WD hitch. I highly recommend the Bullet. Have a 2014 and have not had a single problem or failure of any component. And have only seen positive reviews on this and Keystone sites. Check them out!
