I've had to adjust the striker and the deadbolt a couple of times on ours. I forget off the top of my head exactly where the adjustment is but I'd say it's a standard part of a Vegas 24.1 ownership
The other thing that happens is the door may bind slightly due to frame twist if you are parked at an awkward angle or use leveling jacks to tweak the frame too much ... so do any adjustments on a flat, level surface.
But thankfully I haven't had the door fly open ... that seems
... might make me nervous enough to throw a bungee cord from the stair to the latch if unsure
