Battery recommendations for 1500W inverter
Does anyone have recommendations for a 12V battery setup that can power a 1500W inverter? The background: my travel trailer is currently powered by two 6V golf cart batteries (Duracell SLIGC110 215...

Yes AGMs are the best with holding their voltage under heavy draws.
Ok so the culprit in your case now must be the inverter-battery wiring being too thin and long, and the two 6s being too low or some combination of all that.
You should be able to run the microwave for a few minutes with the two 6s as long as they are over 75% SOC and the inverter-battery wiring is sufficient.
For better results with two batteries you could go to 12s with as much AH as possible, or even better, use two AGMs with as many AH as you can, and go as short and fat as possible with the wiring.
EDIT-- with a TT it is necessary to put the inverter up front close to the batteries. Often the inverter will go in the front pass through and holes drilled through the floor so the wires can go down and under the front cap and up to the tongue battery position. Your shore power cable can reach the inverter up in there. Turn off the converter, put fridge and WH on gas, and you are on inverter "whole house".
