Can I really do this?

I agree that a travel trailer or 5th wheel would give you more band for your buck. Motorhomes are very expensive to maintain. Just think how big those tires are and how much more they cost than say 15" trailer tires.Trailers don't take a lot of maintenance and it's no problem to let them sit for months. You could get a really good used TT for under $20,000 or less. As for $2,000 a month to live on, that is doable. Get the America the Beautiful pass. It gets you into any National Park or Historic Park for free and camping in any federal campground is half price.We stayed in Yellowstone and Cape Hatteras national Park for $13 a night.You get the same discount at Forest Service and Army Corps of Engineer Campgrounds.There are some publications about free and low cost campgrounds.If you don't move around a lot,fuel won't be that big a deal as long as prices stay low.So if you're frugal and use low cost campgrounds, you could probably get by for $400 a month or so for camping fees. If you eat in most of the time you could probably live on $100 week or less. But you need to be able to save some money for truck maintenance and repairs.You have 3 years to come up with a plan so do your home work and good luck.
