Two Battery Bank Question
I recently installed a 2nd battery bank that is connected through a transfer switch that switches between shore power and Inverter Power. This new addition has a battery charger that is powered throug...

On the inverter install, it is right to have the 12v wires to the bank be short, but the 120v output can be on a long extension and no voltage drop with the 120v.
In the 5er we had, I put all the batteries up front with the inverter and a battery charger and ran the shore power cord from the back of the 5er up to the front to plug that into the inverter (converter off, fridge on gas) The power centre was in the middle of the trailer, but the long wires from front to there for the ordinary low amp RV loads didn't matter--I had the high amp charger and inverter up close to the batteries.
Your longer 12v wires to the back from the front batts will not be an issue for running the low amp Rv loads.
You can have both chargers on plus the solar for 3 at once and no problem. Don't fuss that the chargers are not all to the same battery posts. They will add their amps until the charger's voltage equals the battery voltage, so if one has a higher voltage it will keep charging the battery up past the voltage of the other charger(s) until they cannot do any amps and 'drop out' (but still on--just no amps).
You might have a problem with the generator watts though, if both chargers are too much of a load.
That small of a trailer would have problems with weight with all the batteries up front I guess.
