At my work, we had a dozen vans and pickups get flooded with about 20" of water in the parking lot. What they did was change the transmission fluid, and inspect the rear axle fluid to make sure they did not have water in them.
Later they replaced the 5 X 200 HP storm water pumps with 4 pumps - 1,200 HP each and 48" diameter water lines leading out into the LA River. Turns out that one of the 5 pumps had a queen size blanket get sucked into the inlet, and shut that pump off.
Anyway the truck is not 'destroyed'. IT really depends on how deep the water got where the trailer is parked. A couple of inches above the floorpan, and it probably will dry out and not leave behind any bad smells. Yet if the smells are around, then that might destroy the trailer.
What state are you in? You might consider going out to Tucson, where it is very dry! It is a lot cooler than Phoenix, where it might reach 100 soon. There is a Escapees park in Benson, I have stayed there many times. There is a nearby Coast to Coast park as well.
Changing the transmission and rear axle fluid is cheap insurance that they are not damaged. Check your oil. If there are any white specks in it, after running it for a minute or so, do not restart it until the filter and oil have been changed. It is really difficult for water to get into the engine, it is pretty well protected against water going in - because cars drive in the rain.
Good luck,
Fred.
