Looks like there is pass through storage at the front of the TT? This would work great for the solar controller and inverter location and is exactly how I did it in our TT. I drilled a hole in the floor of the pass thru storage for wires which then lead out the front of the TT to the batteries on the tongue. I've got about 5' of cable length between the batteries and controller & inverter.
Wire gauge and distance doesn't matter too much between the panels and the controller because your controller is going to prevent the batteries from seeing the peak panel voltage anyway. Still get as fat as possible, but don't worry about it as much as between the controller and batteries as has been mentioned several times already. If your controller has separate voltage sense wires, it will compensate for the voltage drop on the charging lines. But I think it's still wise to go as fat as possible so you know you aren't creating a bottleneck.
The easiest way to wire up the inverter to power all of the 120V AC outlets is to just plug your shore power cable into an inverter AC outlet. AS you've pointed out, the converter must be turned off.
You are correct that the converter is far from the batteries and there is quite a bit of voltage drop due to that, but who cares once you have solar doing most of the work. My converter has been switched off at the breaker by default and I almost never use it.
