As an aging RVer, I found that tasks such as checking tire pressure and doing other needful services close to the ground has become more difficult, especially when getting back up from a kneeling position. I built a helpful device out of a scrap-wood frame, pool-noodle handles and a couple of cushions. Both the base and uprights are 18 inches. To keep tools within handy reach, I attached a plastic container to the side with screws.
