Success with HWH kickdowns.
We pulled into a site that I knew we'd have problems with leveling. We did, front end waaay down. A forum friend told me about the Camco level indicator, which I bought. Talked with HWH and tried the manual adjust,slowly, by looking at the indicators of the Camco on the kitchen counter. All green lights and double tested level by the 'bathroom door method'. Perfect!
