Boondocking in Mexico

When diesel was fifteen cents US per gallon I ran a genset 24/7 with three roof air units. I had to have a palm frond enramada built around the bus. This was on the coast 6km north of Xcalak.

It is so sad seeing announcements

"Moving Sale. Moving back to U.S. (Canada). Nearly new furniture and appliances. Everything must go. Best offer accepted".

I do not forbid AC for anyone. I have plenty of good, clean power to run two AC's per hook up, as do other RV parks. If you stay long term at an RV park, expect to see some good prices but it is not free. But you do have access to their showers and bathrooms plus what ever other services they offer, like WiFi for example. Boondocking is really not the way to go for any extended time. You need water, a place to dump and a bit of security when you want to leave for the day.

Towing with a 1/2 pickup isn't ideal, even with a 20' travel trailer. Everything is more rugged on a 3/4 ton... brakes, suspension, and usually, gearing.
Mexican roads feature steep grades and fast drivers.
The suggestion to visit Mexico (not the border towns) and see how you like it before getting too invested is an excellent one.
And finally, it's now usually more expensive to travel in Mexico than it is in the US. Most everything costs more.

Heartfelt recommendation. Come down here. Fly. Rent a house. In August. Pass a month or so living here during Las Aguas. Pink Cloud decisions have a near 100% failure rate. RVing the Yucatan peninsula IS NO LONGER CHEAP. Very common for a remote beach to charge a 200 peso daily fee even those with utterly no services. Summer is a freaking FURNACE. Common to see Merida with 120F temps. Tulum with 95F and 95% relative humidity. Cancun visitors dash from air conditioned hotel to air conditioned taxi to air conditioned resturant.

To not to try this out is to almost guarantee failure. You do NOT want to rely on RV parks for your air conditioner. They forbid it. If you can sleep in 85F 85% relative humidity you have a better chance. I live Mexicano I eat Mexican because to do all things gringo style you will pay FAR more than you would in the USA. This is guaranteed.

Money should be the LAST reason to move to Mexico. I have spent 99.99% of the last twenty years in Mexico and have boondocked Yucatan for more than 2-years summer and winter. Yucatan has Jekyll & Hyde like differences between summer and winter.

This is SPECIFICALLY not to discourage you but simply get a glimpse of Mr. Hyde. Quien sabe, you may love it. But going in, you will get to know Mr. Hyde in August and Sept.

I think you're plan is fine, except that a 20' TT is going to get awful small after a while. I've never owned a TT that small, can you get a full sized queen bed in one that you don't have to fold up every day? Shower will be small and very limited closet / storage space.

You might think you'll spend a lot of time outside so the little trailer will be fine. But if you're going to be there most of the year then you're going to spend more time inside to get out of the heat and humidity than you might expect.

If you buy new, see if you can get a 15K btu AC installed instead of the smaller one. With a slightly larger TT you might be able to get two ACs - what happens if one breaks down there? Make sure you get an awning also.

For off-grid the 20' TT may only come with one battery, you need at least two - again check on a slightly larger trailer. Four batteries would be ideal.

Sounds like You have thought this plan out ! Your choice of Vehicles is good and practical! I think that taking them into Belize is Not a Good Idea though!
