No amount of cutting fuel/ignition will prevent this.
Everyone needs to take a deep breath and admit that you don't drive your car or RV anymore. You haven't for years. You transmit desires to the computer and the computer decides what happens. Say you put it in "R".. Well if the computer decides to go forward, that's where you'll go.
This isn't bad. This means that we can still use MPG instead of GPM (gallons per mile) for our RVs. It also means that you don't die every time you go for a drive.
Guys, we are driving 13Ton RVs with across the country every day with ZERO formal training, getting north of 6MPG and putting out less pollution than an econ crapbox from the early 90s..
How friggin' cool is that?!?!
Read the manual, do what it tells you and if something bad happens your next of kin can sue the hell outa Forest River and Ford!
