I measured the door,
The actual door is 29", outside frame to frame is 31 1/4".
When my door is all the way up till the little lock handle is touching the wall there is a 3/4" gap between the door and wall, you could get away with a 1" something and still latch it up.
I wish it was easier to post photos here, I took a couple but I'll have to load them to photobucket and post them, the way my hinge is it kind of crests a drip rail above my door.
I'll measure mine in the morning for you if you don't get the measurement before then. I will also check to see what kind of clearance is there when it is opened all the way and latched.
My left side door does this sometimes but the door itself hasn't gotten wavy or anything, on mine water pools up between the bottom of the door and the housing.
I have a 31bhpr, and it really squats the rear end of my 2005 Excursion. It drops the ball 3 3/4" inches when the trailer is attached (without my equalizer brand distribution hitch attached). Even with the distribution hitch attached I have quite the squat in the rear.
Just yesterday I swapped out the stock Excursion springs for those that were on a F350 (c-code, 3000lb each). I STILL get a 3 3/4" drop when I attach the trailer. Now the F350 springs gave me an 2 1/4" increase to start, but it still drops a lot. I haven't hooked it up with the equalizer hitch yet so I am hopeful that some change will have come from the spring swap.
Is anyone else seeing this with their trailer? I don't even have the water tank 1/2 full right now. Thanks for any info.
That sounds completely normal to me, I would think it would come back up a couple inches after you attach WD bars. I don't think you needed to swap the springs, I would have seen what it looks like after you get the WD all set up and dialed in first.
