I unfortunately only have room for two batteries (unless I totally redo something - I have a Class C where the batteries are under the entry steps) and may consider the AGM batteries when my current set kicks the bucket. Not sure if I can fit anything larger than two normal sized batteries - haven't measured to see what sort of space I have compared to battery sizes.
After you measure your battery compartment come back with the measurements. I would then have some ideas for you regarding battery options. It is an entirely valid approach to maximize your battery capacity based on available places and room for batteries and then size the rest of your system to that. Then you will know what your electrical power limitations are and how you will have to accommodate those in your usage.
