Our camper (Lance 2075) has an indoor bath/shower. The hot water temperature is set at approximately 115 F. I can understand that 68 F doesn't feel warm.
1) We carry 20-25 extra gallons of water in the truck bed. I like taking a shower with soft water from home. And my wife struggles with “army’ showers
2) Induction hot plate is a must
3) Keep your favorite beverage in a cooler to keep the refrigerator door closed
4) TPMS on the trailer tires...
