We are pleased with our choice of model and Georgetown in general. Our RV Dealership suggested putting in 100 lbs of pressure for all 6 tires. If you look at the specs for the respective tire you own, it would be based on the axel weight for front and back axels individually. You will need to weigh you coach and see what the weights are and use the formula you can find on line for the tire manufacturer. We had done this and have our front and rear tires at 90 lbs. The ride and handeling are very much improved.
We also chose the industrial frige which runs only on electric and not propane. This has its limitations when you dry camp. Be sure you have your house batteries charged to max or the cooling will not last the night.
When traveling, ture on your inverter to allow the house batteries to charge. When you arrive at the campsite, keep main power swith on and inverter off when you connect to shore power.
Uncle Al, I noticed you are a Georgetown 378 owner. I just bought one and am looking for helpful hints. Any to offer? Interested in tire pressure and how well the refrigerator works while driving down the road using the inverter.
