Sealed or AGM batteries are considerably more expensive. I have never minded having "wet" batteries in my RVs or boats. I check them once a month and add water as needed plus it gives me a chance to make sure everything else is good in that compartment.
A couple golf cart batteries would certainly give you more power longer. Make sure they are hooked up correctly and your house charging system is good to go with them.
