There are other suppliers for DC/DC converters you could look in to one of these, however, I would first check the ratings of the original and replacement unit, and then measure the connected load. Inverters will power an overload for a while and then fail. You will need a digital meter capable of measuring 20 amps and you will need connect this to the 12 VDC output terminals in series with the connected loads, and you will need to turn on ALL of the loads to see if the unit is overloaded.
You should be able to relocate the inverter if you think water is causing the problem.
