We have a 2003 R-Vision Bantam Trail-Lite that I am doing some work on before out first trip with it in two weeks. We had a ton of rain and found a leak in the front bunk - fortunately the only leak! It is where the bunk canvas meets the frame in the upper corner. The canvas does not appear torn or have a hole. honestly it looks like it has been like that since new or at least a very long time. It is a bit tucked under the overhand of the bunk opening so it isn't as if there is a steady flow of water coming in, but in heavy rains some of it works its way in and gets the corner of the mattress wet. Below are some pics from inside and out as well as the other side for reference. Given that they used some kind of flexible sealant from the factory I was hoping I could get by with doing the same now. I would put in some temporary backing on the inside so it wouldn't ooze in and then fill it from the outside. I was thinking of using either some ProFlex RV Sealant or some Flex Shot Rubber Sealant. I can't find any examples of anyone doing this kind of patching online so I thought ya'll might be able to help.
