You may need to do the roll-up flap on the rear door but I'd prefer to see a D window on the sides. Roll up flaps are all or nothing with no way to ventilate at the top as is common practice on modern tents. Also the roll-up style can be very tedious to operate from the inside.
Jeff, a few thoughts:
- Having the side window solid flaps on the inside is much more convenient. Want to be able to adjust / open / close it at night without get out.
- From a ventilation in rainy conditions standpoint, you want side window to zip down from the top.
- Triangular shaped side windows with two straight zippers will be a lot easier to sew and cause less puckering.
- To handle fabric stretch / shrinkage and because TrailTop components for other applications and Dinoots do not have soft top retainer panels I would propose a bungee and knob bottom attachment method.
- For the door flap, make it hang down 4-6” pass the top of the tub and sew in a sleeve that a piece of ½” conduit can slide into. This will weight it down nicely without the need for snaps and makes rolling the flap up easier.
- I would sew the three sections together, that zipper would likely end up being a leak source.
Taupe and olive combo is my vote.
