Hi Jay...have a look at the pics I've posted about the seatback etc.
We decided that the forward end of the seatback position would be
comfortable if it lined up with the inside of the front bulkhead. The
seatback is approximately 12" wide and has a piano hinge to form the
wingberth. From our experience with our trailertri 720, there will
rarely be water in the upper folding strut pivot area. Therefore
water should not be an issue.
Also shown is the storage compartment behind the settee. We decided
that there would be easier to access the storage compartment by
hinging the berth panel up rather than lifting the seatback to get at
We also chose to narrow the starboard settee by about 2" in order to
create more legroom. This still leaves enough width for a comfortable
settee but could be too narrow to use as a bunk for an adult. We are
planning to use the starboard wingberth rather than the starboard
Re the Head area: rather than have a lifting panel on the starboard
settee to access the head, we chose to taper the forward part of the
settee so we would not have to move another cushion. This will allow
us to make one starboard settee cushion only.
