Company in US which ships to Mexico

I can tell most of the responders have never used a carrier like DHL, or FedEx to ship something like a black water tank to Mexico. The charge will be I assure you at least four hundred dollars. There is a huge penalty for oversize items.

ESTAFETA (google) is the carrier of choice INSIDE Mexico. Go to your local office of ADUANA (SHCP SAT HACIENDA) explain your problem. This will allow, with that same letter sent to the importer the tank to pass into Mexico duty-free.

GOOGLE RV suppliers in EL PASO TEXAS, then telephone them to make shipping arrangements.
