On the RV checklists I never see knee pads. They're the greatest. I accidentally came upon the cheap foam ones on sale for 5 bucks. Now they're right up front in the Dolphin's basement storage. Setting up the stabilizing jacks, at the dump station, if I ever had to change a **** (I'm not going to say it, I don't want to jinx myself). Knee pads. Must have.
