First trip with my first RV

A few more recommendations: When driving in hill country use second gear to help control down-hill speed, don't ride your brakes, they may overheat and fail. Use second gear when climbing steep grades, let engine rev and not "lug" to avoid over-heating your engine. Don't let impatient people in cars behind force you to drive too fast going around curves and risk losing control. Pull off the road and let cars, truck and motorcycle drivers get by but only in designated pull-off places. If you go at the speeds posted on yellow signs, around curves, you will normally be safe when roads are dry and clear of debris. Learn about the 12-volt DC house batteries and 110volt AC "shore power" systems and including the converter charger and how to properly start and stop the RV generator, air conditioner, water heater, furnace and how to operate the TV antenna and cable TV. Stop at rest stops every few hours to relax and walk around. Find an RV Park or camp and get settled in for the night during daylight when there are still vacancies. It's is awful trying to find a place to stay at night when you and kids are tired, hungry and irritable.
Have a decent set of hand tools, a multi-meter, electrical tape and some crazy glue, and variety pack of fuses. Know where the circuit breakers and fuse boxes are located.
