Sealed batteries don't have to be AGMs. I use sealed marine deep cycles in both my Class A and my Class B. But for sure sealed batteries are best for confined spaces with poor ventilation.
I thought those wet sealed were starting batteries. Do you have a link to those batteries so I can review the specs? My details are in my profile.
The AGMs are hybrids with both starting and deep cycle service specs.
I used an inverter to run a 900W electric 120V kettle with my 79AH AGM for 7 min to boil a quart of water. Would an equivalent AH wet sealed do that without exploding?

My B van is a Ford Hi Top that I converted to a camper myself. I have both 12vdc and 120vac installed.
In the B van I run a 900 watt inverter off a group 27 marine deep cycle to run my micro wave, TV and frig when not on shore power. The frig runs as I go down the road. The micro draws max amps from the inverter but I only use it for a few minutes to heat a cup of coffee water or warm up food. The battery also recharges off the engine alternator when I turn the battery select switch to on. No explosions in 5 years haha with the B. And no explosions in 50 years of boating. Explosions are most frequent when a vented battery releases hydrogen in a confined space where the gas can accumulate. It only takes a small spark.
You can get specs from any of the major battery companies like Johnson Controls, etc. Or you can go to a West Marine web site or catalog for marine apps. A marine deep cycle works very well in RVs. They come in a variety of sizes with 24 and 27 being the most common. There are also high end upgrades with larger capacity (think more lead plates and weight) at a substantial price increase. I paid $139 each for a pair of standard Group 27 sealed marine deep cycle this year for my RV house batteries. I hardly ever boondock and only overnight when I do. I have used marine deep cycle batteries in all the RVs I have owned and never have had a problem.
