Hey Jason, thanks for reaching out!
Yes, you can use the Weigh Safe Flap Jack Folding RV Stabilizing Blocks # WS78ER for holding your slide-in camper up with the HappiJac system.
An alternative is the Lift Extenders Kit # LC182495 which offer a 6" lift and are installed directly to the HappiJac jacks - so you don't have to remember to pack them up OR set them up.
Will the 6" lift work for your application? Or are you needing the 8" lift specifically?

thanks Jon. I'm looking for something with a larger footprint that offers more stability when the camper is off my truck and thought these might be what I'm looking for. Currently just using foot long sections of pressure treated red cedar 4x4's.
