Is this a possibility?

Have a portable self contained 12 volt solar generator with 4ea 6 volt full river batteries. My RV currently has 2ea 12 volt house batteries and a separate 12 volt battery located near the on-board onan propane generator. My current set-up plan is to sit the solar generator in the sun and park my RV in the shade and run an 110 volt extension cord in-between (during heat of summer).
My question - If winter camping someplace and the solar generator could be sitting very close to the RV (within 10 feet say) would it be possible to connect the solar generator batteries to the 2ea house batteries (with jumper cables or heavy gauge wire / anderson connectors)?

I would still have an extension cord attached between the generator and RV and would of course have to turn on the inverter to generator 110 volt from the solar generator, when needed, but if I could connect the 2ea battery systems directly it would eliminate the need for the RV converter to have to cycle to charge the 2ea RV/house batteries. I don't want to damage either battery system. The solar generator has a battery monitor so I presume if the 2ea battery systems were hooked together as a second question would the battery monitor also be monitoring the 2ea RV batteries since there are all connected together?
