you could leave the sheets on the mattress and maybe a thin blanket and still fold it. that's what we usually do.
or take the mattress off the bunk end and lay it over the dinette, made up.
otherwise, the mattress has to be folded.
and i agree with the others about not having to close the bunk ends when we leave for sightseeing. we have NEVER had to do that.
and we've owned ours for nearly 10 years.
plenty of non-hybrid RVs get broken into. look at all the posts from owners who have had their RV broken into at the storage yard.
if someone wants to get into any RV, hybrid or not, they're very easy to get into. Heck, most use the same dang key for the doors.
as far as cold/wet weather, we've camped in snow and torrential downpours and had no issues. snug as a bug in a rug!:B
but we use PUGs and Reflectix, so we stayed quite warm and dry.
