What you want is an auxiliary evaporator, either for the living space or the cockpit or both, that runs off the existing A6 compressor. If you decide you need cooler in the cockpit, install something like the "vintage air" unit from AppliedGMC and install a shower curtain behind the cockpit seats to keep the cool air up front. If you want BOTH a cooler cockpit and cooling in the living space, install both a vintage air like unit AND an aux evaporator for the living space and disconnect the OEM evaporator. I am not sure the A6 can run three evaporators.
Post back here if you have trouble finding ideas for an aux evaporator on the photo site.
If you don't have OEM dash air, the only practical choice is to get the Onan working, reinstall it and the roof AC, and run the Onan to run the roof air while underway. Either that or find a 1977 or 1978 GMC that is being dismantled and transplant all the dash AC stuff into yours.
