I?ve got a 24 ft Starcraft and i wanted to inspect the brakes. I?m got a big floor jack and a bottle jack but neither reaches the frame. I?ve some good sturdy jack stand but they don?t reach either. I could stack up concrete blocks or wood but that?s a bit sketchy and not easy to do safely on the side of the road. What do you guys do? It?s dual axle so I could use that curved ramp thing but I don?t know how good that is.
