I did nearly the same thing to my last 2 travel trailers and will likely do it to my current toy hauler before spring. On the travel trailers, I ditched the el cheapo batteries that came with them and bought some nice sealed big AGM batteries. The first trailer had a 758# TW on a 3330# empty TT. The second TT had a 864# TW on a #4300 empty TT. Excessive for both. I have borrowed a 1000# scale to find this out. First TT got a group 31 diehard platinum under the sink, barely fwd of the axles. Second TT got 2 Exide group 31 AGMs in a rear storage compartment. Neither were hard at all to rewire and I did upsize the wire even though they moved closer to the converter. For what you might spend on access doors and undermounts, you might be close to the cost of some sealed batteries and save yourself some work.
