Welcome to the forum!
What converter do you have now? And why do you feel the need to upgrade?
In my old HTT I had a "dumb" Elixir converter, so I added a separate deck mount IOTA 55 for better charging off a generator. I took the IOTA and mounted it on the ceiling of the front pass-through of the new TT, giving me a 3' cable run to the batteries. For AC power I added a line tapped off one of the front outlets, drilling a hole and adding an outlet and switch in the pass-through. The original WFCO got put on its own breaker so I can turn either converter on or off. Overkill? Maybe, but WFCO converters aren't known for going into bulk mode easily, and some cg's we go to have limited generator hours.
If you still want to upgrade the converter, I'll add another vote for Randy at Bestconverter.
Yeah, I know - solar. But a lot of our favorite sites are shaded so I didn't think solar was a good option in my case.
