Back in May during out camping trip the weather a bit challenging raining every now and then. Since we were inside the camper at the time we notice a trickle of rain water just under the window to the left of the main entry door. after the rain finished we dryed the area and I added a little more sealant to the the outside of the window. I haven't seen any more leaking. However, the wall started doing this shortly afterwards. The unit is still under the mfg 1 year warranty. Please advise on next steps
