The Sunbrella fabrics for awnings will work. I used their fabric called "Surlast" for my Campster
popup. It has a urethane coating on the side of the fabric that faces to the inside. That coating makes it very much waterproof from any rain. You can't see the coating easily, you have to look at it closely. But you do have to pay attention to which side faces out when you fabricate the canvas top. Be sure you seal all the stitching lines and seams on the inside of the canvas top after you sew it. The same as you would with the rain fly on a tent or the seams on a tent.
of the Surlast is just right, it is not too heavy compared to other Sunbrella products so it folds easily but it is very strong. I have had my popup section up most of the year for the last 3 years and it is doing great. No water coming in but in this cold rainy weather because it is waterproofed I do get some condensation on the inside surface of the fabric. At first I thought that was moisture coming in from the exterior but that was not the case. Just the normal condensation stuff that happens when you are in the trailer full time on cold and rainy days doing cooking and breathing. I just use a microfiber towel to dry it off on the inside in the morning.
Just a side note if I ever need to make a new canvas for the top I will then choose the color white because it lets a lot more light
come inside. With the low ceilings these are not the brightest trailers on the road and the white fabric would help that issue considerably. I also would make the zippered opening section out of a good quality clear vinyl such as is used for the rear windows
in convertible top cars for the same reason, more natural light
coming into the trailer. You can always create a fabric panel that attaches with Velcro to put over those clear, zippered "windows" if you want to block out the light
At some point in time soon I will create some panels of Reflextic to insulate the interior side of the canvas area for cool season camping during the night time so it does not get that condensation issue. I do like having the head height and I like leaving a little bit of open area at the top of on those zippered sections for fresh air exchange when it is raining outside and also for night time sleeping. But if it gets really cold such as in the 30s (or super windy) then I lower the popup when camping. But in this 40 and 50 degree night weather I usually leave the top up especially if I am heating with electricity using shore power at a park.
