Not only the entry door but all the compartments on the coach have rubber gaskets that tend to be sticky when new. Liberally spray all the rubber gaskets on your coach with silicone spray then wipe with and old rag to make sure there is a good coating ALL the way around, make sure you get the top of the door. Should take care of the sticking problem. The access door to our propane was stuck so bad I had to use a screwdriver to pry it open. While you have the silicone out go ahead and do your hinges and locks too!
