2014 Bounder is a Gas RV. But still has automatic leveling jacks. Never park where you have to lift the rear tires off the ground. No, not even if just one side.
Where your old 5th wheel balances like a teeter-totter. your new fleetwood has leveling jacks. either electric or hydraulic. It is built to squat over the levelers. you'll find the square stackable interlocking blocks, placed under your levelers are the most popular. unless you have space to waste storing the Anderson's, then go for it.
What you have will work in a pinch, but I would recommend staying mindful to park nose slightly lower than tail. And don't use anything extra unless your coach can't find 'LEVEL' on its own.
