First, Marley has not been manufactured since the 1970s.
Second, OP: You didn't say if your application is for Touring or
House use, but the one you have found is awful. Send an email to
All Access Staging & Productions and/or
B and R Scenery: Contact Us and see if they have any pictures of theirs. The
one you have found is horrible. Gimme a day and 200' of 2x2 SqT and $100 worth of misc. materials and I'll fix you a better one. Where's the detachable crank handle so one never has to pick up the rolls? How can that thing pack in a truck? Fork pockets? Tape storage in the unused/wasted space?
The Rock Show carps are more advanced in so many ways.
