We have a Flagstaff 829BHSS, we did not bottem out when we traveled, but we had problems with inclines. We are a low profile (and we do sit close to the ground compare to other styles). We had to get skid wheels to get up our small incline on our driveway. We would have taken off our waste lines (
) if we did not get skid wheels, but be careful get a good pair we got 5" and paid about 139.00 for them.My husband did not want to drill into the frame so this is the system he came up with, we have never had a problem with bottem out now that we have them installed. My neighbor bought a cheap pair and he took the off the first time he tried going down his driveway. We also had the RV dealer adjust the hitch system as ball part was sitting to high and forcing the rear of the camper down. We also have air suspension on our Navigator which is always adjusting to the load which sometimes works against us before the adjustments. Not sure if this helps, but you are not alone with low ground clearence.
