My 1676 2176B needs more than that, but the main problem is I t needs some work on the hydraulic pump (hopefully just brushes).
Using the "Search" above it takes you to several suggestions, but this one,

In May, I "upgraded" from my 41 year old 2176B to an only 17 year old 2600TFB. Still, I usually sleep in my Van, and let others sleep in the Hi-Lo!
