Also, when the door opens it slams into the awning brace.
I had this problem also. I fixed it by unscrewing the lower arm from the door bottom that limits the door opening and then closing the door closer to a 90 degree angle with the HTT side, then reattaching the plate on the door, so that it was further from the hinge. This limited the travel of the door. I did this because opening and closing the door with the awning deployed was a problem. I think this was an oversight during construction, because with accurately placing that arm plate on the door bottom, you keep problems from happening.
I thought the admonitions of not using the stabilizers to level the camper were all wet... I figured an inch or so of leveling capability would not hurt... I was wrong... I also worked into a door closing problem. I solved it by bringing up all stablizers, then rolling the HTT onto two stacked 2 x 8 boards on one side to get the side to side level. I used the tongue jack to get front to back level. I laid down 2 x 6 by 10 inch long boards and re-stablized the jacks on the boards, because I am on gravel in my driveway. I only just brought them into contact with the boards, then gave another very short burst on slow speed on the electric hand drill. So far for the past 3 weeks setup in the driveway everything has remainded level and the door closes properly.
