The weak link in Pleasureway's system is that everything runs off an 8 gal propane tank (including LP heat, an LP generator to run the AC, an LP water heater, a 3 way refrigerator that needs to run off LP while traveling plus the cooking stove). You are going to be filling that propane tank a lot.
They need to convert some of these appliances to diesel for their Sprinters (ie. 2nd alternator, Espar heater, compressor refrigerator, etc.). Multiplex wiring and tablets don't make up for their old school appliances.
