When you connect multiple battery banks on those terminals you are putting those batteries in parallel with each other. Hooking up your starting battery that way means you can drain it dead if camping without shore power. I would not do it without adding a battery isolator, so that the start battery could charge but not be used for house power.
Furthermore, I suspect your 92 Pace already charges the starting battery from the house system. I know my '96 did - there was a RVP battery charge controller that handled that.
