Sounds like a great plan and a lot of fun. But I'll echo what someone else said and suggest you consider a small "Class C" motorhome instead. Lots of these available used. You should be able to find a good one that will carry you cross-county and back for $20,000 or less. This will leave you some cash leftover to get off the road and stay in local hotels, cabins or B&Bs when you feel like it. You could consider paying for a roadside assistance program like CoachNet to help handle any breakdowns that might occur on the road with an unfamiliar vehicle (less than $100 for a year's coverage).
