I tried a search and did not really find what I was looking for so here it goes...
We currently have a 2009 Rockwood 2306 and for the most part love it. Only had two complaints:
1st, the queen bed sits sideways (no prob) but the support for it stopped 3/4 of the way across so the person sleeping towards the rear of the trailer had half their body just float in the air. terrible design, but fixed with some extra plywood from the garage.
2nd and the reason for the post. The 2306 only has 7" of clearance between the sewer and the roadway with the WD on. With WD off gives me just under 8" (truck sags and gives a bit more height to the rear). For me to get into the driveway I need to dump the WD to guarantee I clear the sidewalk between the apron and the sloped driveway (apron angled up, driveway angled up, and sidewalk flat/ level with the world). The sewer hangs below the "skid bars" in the back just rear of the wheels.
I did break off my gray water connection once due to the low clearance. Thanks god only the gray was affected and it was empty....
What are the clearance heights now? Have they improved? I would love to stay with the FR family for my growing family but I need clearance w/o needing to buy lifters and risers and all that. Thanks, Pat
