The Tuscany has 3 AirExcel heat pumps and it takes all three when it is over 100 degrees and in direct sunlight. Being primarily Black sure don't help that and we do have double paned windows plus dual shades.
It will maintain target temperature but creates plenty of noise.
The last camper we had that was adequately cooled with one ac was a 24 foot TT
The Landmark 5th Wheel took 2 units running if you wanted to get below 80+
Park voltage can be a big impact if it is low when everyone is cranking up the AC
