Thread resurrection!
The elbow tip is a good one and I have a semi-related problem. I am going to install my Propex in the rear of my Jeep (up high under the fiberglass roof) and need to find some sort of bulkhead connector for 60 mm duct. Does anyone have an idea? Can't find anything.
I need some sort of weatherproof-ish bulkhead connector to pass the duct through the fiberglass top (a set actually for supply and return). Then I need two more to pass through the fiberglass bottom of the RTT. AT this point, it would be awesome to fit some sort of sweep 90 for aiming the hot air and some sort of ball-shaped screen to keep the return from getting covered up with blankets and/or dogs during the night.
I'm planning to make it a straight shot through, but it might be smarter to use 90s between the roof and tent incase I want to slide the tent forward or rearward for any reason later.
