I would have an isolator in the circuit if one is not already in between the two batteries
If I had the inverter and front compartment battery it would have to be a Grp 31 AGM and the main batteries would be two GC2 flooded cell batteries...
footprint of the GC2 is the same as a Grp 27 and two Costco GC2s are about $98 each... Mine are currently Seven years old and as good now as day one..
The hyd system runs very niicely on the GC2 batteries and it doesnt take long to fully charge them after running the Hyd system for my hyd slides and six point hyd level up.. about 15 to 25 minutes max time for batteries to be fully charged

I am defiantly leaning toward making it two separate systems versus wiring the batteries in parallel and draining them as a unit.
I don't know that I really need two GC2"s as opposed to one Group 31 for the house. In the past I've always used a single group 27 and never had a problem with it as a whole house battery.
I guess my next decision will be whether to use an isolator and let the WFCO 8955 charge both batteries or put another independent charger beside the inverter and wired into the A/C side of the trailer..
The Isolator would certainly be less expensive.
Since I already have one of the 80 amp Bussmann Circuit Breakers in the side compartment for the hydraulic system;
I'm going to replace the other two 50amp auto-reset with matching
