I was wondering the same thing. We just took delivery of our 29M two days ago (hello everyone!). When transferring stuff from our 5th wheel, the 90 degree opening became a bit obnoxious. Has anyone considered installing a good old-fashioned "keep the door open thingy" like many travel trailers have?
I almost cringe at the thought of adding something like that to the beautiful surface of the MH, but it might open up a whole new world.
