BUY USED, BUY AFTER LABOR DAY, BUY FROM ANYONE BUT A DEALER. Window shop at the dealer. Buy after labor day, road test the new camper, then winterize it. OR if you decide it's not you, winterize and resell in mid april, may.
Based on your vehicle an A-liner, or tent, would be your best bet. Hard sided will be a death trap on anything over 4% incline. Factor in water (8lbs per gallon) gear, food etc you'll peak out before you're fully loaded.
We fill up close to our destination, if not at. Based on your vehicle, i would buy a basic A-liner, use a port a potty / Luggable Loo, solar shower , use the melted ice water for cleaning dishes etc.
Option D would be a slide in unit for the taco.
OR buy a 10-12' enclosed trailer, air mattresses , small propane stove, and enjoy the weekend. Our 12" trailer is storage and or camper, as needed.
