I couldn't imagine giving up the rv although it's only been used a few days in the last year.
That said, the last couple of years we have taken car trips staying in Airbnb. The prices run the gamut but we've never paid more than $50 a day and gas savings on a small car is incredible.
Other trips have been taken (prior to the pandemic) via Mexican airlines and Airbnb. We've been to Ensanada twice using Vivaaerobus at $100 r/t (three-hour flight) rented a house for the week at $30 a day. A 24 hour car rental took us to the wineries and the next morning La Bufa and the rental was 800 pesos with insurance and a full tank. Same price structure with Mazatlan and the hotel was on the beach and we don't stay in dumpy places but we're good deal shoppers.
Boondocking still tops the list. I've never stayed in an rv park in Mexico that I liked with the exception of Hacienda Contreras in Jalisco.
