I have heard good things about the CCV product, but honestly I'm scared of the customer service and the install of the CCV. If they had good reviews of the installation process I'd probably choose CCV.
Good to hear the sprinter has a decent mattress. How do you find information like that? The Sportsmobile doesn't have the greatest list of info on specifics.
I did have a question on the height of the canvas for the penthouse. I will be making my own insulated liners (it sounds like the ~$700 SMB canvas isn't much) and I'd love to know the dimensions, height and width of each of the panels.
I have just seen the interior of SMB's sprinter bed. The mattress is about 4" thick as opposed to my econoline mattress which is 2" thick.
I had a great experience with CCV. However, they did a full interior buildout as well as the pop top and had the van for 6 weeks. The best part about their bed is that it's tall enough to fully sit up up there.
