Get a Sure Power 200 ampere model battery divider solenoid and a 120- amp rated flat mount circuit breaker. No 6 AWG wire is plenty big enough. Pass wire under the truck sheathed in 5/8" heater hose or black spiral wrap nylon sheath. Buy a hull pass through fitting from West Marine. This stuff is a Do-it-Yourselfer's Paradise and ends fiddle------- around with switches and crystal balls. BERG and POLLACK both make 2 conductor no-screw-around socket and plug for truck to camper disconnect.
Such a system will allow your truck alternator to pass a 90 amp charge rate to the GC220 batteries. You do want to recharge them from the truck during ypur lifetime, right? Wouldn't hurt a bit to add a 2nd breaker on the camper side of the plug.
I've installed multiple systems like this and no way in hell is manual switching better. My bus has 2 group 31 starting batteries a 4 L16 house batteries. I forget they are there. The Sure Power charge divider RELAY does all the work automatically.
It would be of help to know what chassis you have. Ford, GM and MoPar alternator regulator voltage set points are different.
