I feel you pain about NYS parks, shade, and solar. That's why I don't have any solar panels.
Our old HTT had a single-stage converter that I supplemented with a deck-mounted 55A IOTA. The IOTA now resides in the pass-through on the new TT and has a 3' wire run to the dual G27 batteries and is on a switched outlet. The WFCO converter in the TT is now on it's own circuit breaker so I can run either converter depending on the situation. The TT also got LED lighting before it left on the first outing.
Look at your battery charger carefully. My 2-10-30A Schumacher charger only went to 30A for 30 seconds "on" and 60 seconds "off." No such problem with the new converter.
