From the fact that you state it was SET to 70 I deduce that you in fact thad the front ROOF AC running and I assume you had the generator running as it is 120V powered and not powered by the inverter, so on the road you must run the genny.
All that being the case.....
By it's lonesome self the forward AC will not cool that bus on the road in that heat. So you have to also run the dash AC and the rear AC. Then it should keep up pretty well.
There's a lot of roof, window and side wall in these things, they heat up pretty good. Takes a lot of cooling to keep it down.
