Indeed... fat-a$$es on some of these ....
The narrowest combo. I have seen is the 8" Jesses @ 33"
BMW Varios come in @ 36" (when collapsed)
The widest a$$ award goes to the big Holans @ 46"
I have a spreadsheet with the data... not sure how to post it intact...
most numbers I have scavanged from other places ... so this is not an "original work"
