Not sure what you mean by access door (entrance door)? I just ordered a door gasket from Inland Rv a couple of weeks ago. I haven't installed it yet, I held a small section up to the door and I expect it to work well. If you are talking about battery, storage compartment doors they have those gaskets as well. The folks at Inland are very knowledgeable and if you have your model and serial # length etc they will get you the correct part.
