storing trailer in Mexico

I bury tires 3/4ths the way into the ground, then use BIG RIG TRUCK RATCHET STRAPS tossed over top the rig and fastened to the tires. Cargo nets, more rope whatever works to spread the clamping over a big area. The cargo straps will hold many tons of pressure and they are rated for sun and hurricanes. I ran the tarps under the rig then used bungees to hook through eyelets and onto frame supports, whatever. The edges cannot be allowed to flap or they will tear and fray. I had to use two dozen bungees and ended up buying a tarp grommet kit to add grommets wherever I liked.
