Tongue Trailer kit includes Tongue Jack Kit, (4) tire protectors with (2) sets of Drive On Chocks, and (4) 7.5" stabilizer pads. With this base kit, drive up onto the tire protectors, be properly chocked, and then use the tire jack stacking stabilizers to "un-hitch" and the R75 stabilizer pads to keep the the stabilizers as wide as possible to make your RV set even more stable. Wider stabilizers are ALWAYS better
