-Have two large bays, with slides. Yes, some lost height storage, but would not be without them.
-On half bay pass thru. No slide. Works well for outside carpet, step ladder, and other long items. With careful packing, I can also store the emergency flashers, small ramps, wood, etc. to one side. These are items not taken out very oftern at all, with exception of the ladder, which is the 'dividing' piece.
-We are at 40', with tag, and frankly would like to have another bay of storage. The Catch22 of the tag's extra CCC capacity, is that lost of storage space to use it
! A 42-45' usually gets you the extra bay that may be missing in a a 40'.
It is surprising how non heavy items can really jam a bay storage up quickly. Chairs for example, take lots of room but have very little weight.
I would not change what we have done. We went with the 40' for pur home parking when not un use, and it sticks out just a bit more then is legal...So for now, with this home storage area - 40' is our max...
Suggest you decide how you will use your coach, make your Pro's and Con's list - and decide what works best for you.
Best of luck, have fun, be safe,
