FR A-Frames have torsion axles, so no "flipping." But there may be other ways to extend the lift of the suspension.
For those who don't know what flipping is; for single axle campers that have leaf spring suspensions, the axle normally bolts on top of the lowest part of the spring arch. "Flipping" means bolting the axle below the spring, giving the camper a few inches of extra height. Axle manufacturers sell a kit for this.
