Travelling to Mexico or South America it is good to have both names on the RV, toad, trailers and tow vehicles if anything happens to one spouse the other spouse can either move or drive the units, and return them to the border, Mexican law enforcement and government types are rather sticky with who's name is in a document as well as some of the South American countries, they love to complicate your life but that is the way they work, one needs to adapt to the idiosyncrasies of the country.
It is a good practice to have all documents copied and carry them in a small safe in the RV, marriage license, drivers license, passports and specially the visas and vehicle permits, ETC.
We have a small safe that resides under the bathroom sink where the water pump and the accumulator hang out, on a shelf that I constructed for it off the floor no water damage should there be a leak, in order to access it you need to remove a panel, no one is going to look in there should they want to rob, we do not carry anything worth stealing, wife uses very little jewelry and it is easily replaced not expensive, $200.00 Dollars and she will get more than what could have been taken, the good stuff stays in the home safe while we travel.
