What brand Pop top-
SMB- Long history, good customer service, at least 3 locations. Gives somebody 5-10'' enough head space to walk with the top down. Overall its a really good top and the install was done in a day. I have been happy with it other then small small things. There is a spring that is inside a channel that rattles when the top is down. How that Mark (MSD on Forums) is helping CCV in Colorado I would actually give them a shot. More head space, bigger bed, and more insulation
