Run both units and try to get it cold in the morning, so hopefully, you only lose ground slowly over the course of the day.
Yes and don't start in the morning when you wake up. A/C needs to run all night probably set at 68 or lower. Put an extra blanket on if by some chance you get chilly. Never stop the A/C from running.
If at some point the units seem to be blowing and cooling less you may want to check if they are icing up. This might seem odd in the desert but with showers, cooking etc there can still be significant humidity in the RV. Remove the lower trim and look for ice on the evaporator coil.
