Should we Rent or Buy an RV?

Realize my plan sort of requires you to be saavy with checking out used RVs and also not super particular on the model. You’re not buying it for a lifetime, but rather for a month trip and say a years ownership (so you can sell it again in the spring).
IMO, the trip is not about having the exact dream RV, but about seeing the country with the camping/RV experience. Buy the one that’s the best shape for the least $ that has the biggest tanks and fridge you can find.
I’d still play the used private party depreciation game over buying from a dealer.

I agree with this. If they are looking for a particular make, model, floorplan, then they are very limited as to what type of deal they might find. I'd also add that Winnebagos usually get a higher price for a comparable size of another make, so they may not find a good buy in such a short time frame.

The OP is also buying at the beginning of high season and selling in low season which could reduce the margin even more.
