Rather than an AUTOMATIC transfer switch, you might take a look at a simple manual transfer switch from Sterling Power. It would let you choose between shore power, a generator, or a large inverter quite easily.
AC Crossover Switch
These would work nicely for a 30A RV, but are only two pole and so would not work for a 50A RV where one needs to switch the two hot legs and the neutral. (In a typical fixed building application, the neutral is not switched, but it must be on an RV.)
The general idea of a manual transfer switch is entirely valid and reasonable, of course. I'm a bit surprised they are not more common on RVs.
