Ok - I went and got the awning pieces and the vent pieces.
Vents are Dometic RM1222 and the matching upper one VT2411
RM1222 measures 22 X 12 inches and VT 2411 is 7.5 X 22
I forgot to count but there is easily a dozen pairs.
There are also some that look a lot like the RM1222 but have no name and measure 24 X 12 inches
There is a water heater door measuring 18 X 14.5 inches and a Norcold Fridge
vent measuring 20.5 X 11 inches
The "slide awning" is maroon and measures 6 feet long, extends to 3 feet and the window awning is 26 inches long and extends 2 feet
There are pairs and some singles of the awning arms.
I will try to attach a picture, but all are similar to the A&E 8481000-401E
That one is 75 inches tall when folded flat up against the wall of the RV and extends from there as well as having its brace unfold up to the top as well. Those are rectangular in cross section and are 3.5 inches by 1.5 inches, measured at the travel latch or mid point. They fit a 3 inch top mount bracket and a 3.5 inch (center to center) bottom mount bracket
These are NOT the kind of awning that fit a 13 or 15 footer - they are the type that fit giant moho's and are often powered awnings.
They are the ones that go on the larger Bigfoot
