An AGM battery will give you no grief about noxious gasses or spills. It is a sealed unit. It will also give you horrible service life when used in a deep-cycle role.
At the campground this weekend, I noticed at least one camper had used jumper cables to parallel-up two batteries (one on the tongue, the other on the ground) to give greater run time.
That idea won't work for an inverter located at the other end of the RV since the line losses for the 12V wiring at that length, will leave you with 9V when you turn the TV on.
