Hello! We are long time trailer owners (15 years) but 1st time toy hauler.
I have a couple questions for fellow toy haulers. Ours has the garage and drop down top bed, and/or drop down bed/dinette . Can both of these be left down when traveling but not hauling our side by side?

Question 2: on our last trailer we had this bar and hook door prop..amazing device. I had picked it up somewhere, and now can't find anywhere and need 2, any ideas where to find? Thank you!
