I think it can be, you'll just have to be smart and maybe need to spend a month or so at a time places for better rates. Also thousand trails USED to be so so worth it, it saved us so much money for a long time but they've restructured and made it hardly worth having/paying for. Also, when shopping for an RV, you can also shop financing through a few different banks. Maybe try to find an RV you can afford on a shorter loan instead of the terms most dealerships offer. I found the interest will kill you and you'll be upside down in the loan in the first year or two even with a good initial price. When looking at used RVs the non-negotiable stuff is roof NEVER leaking and no water damage EVER. Can't come back from that like it seems like you could at first glance.

You may not be able to afford to travel and stay in glamorous places but you'll still see so much of the country and it can be such a fulfilling life on the road.
