I have a customer van in the shop right now with a SMB top that is new within the last year. The fit is ok (just ok, not great) against the roof line but the gasket has already been damaged due to poor assembly. The top has been up and down two times total. You'd think the gasket would last longer than a drive from CA to OR....
The trim job inside was terrible. This will be the second van where I've completely torn out all of the SMB trim/upholstery and started fresh. It's like they put the new guys on the E-series tops or they only do them at 3:30pm on Fridays.
The frame and lift mechanism is bent and no one has even been in the penthouse bed yet. There's no structure to the frame to speak of and I'll have to reinforce a lot of it so the roof doesn't cave in when two people are up there. SMB was nice enough to put a 2x4 across the back to hold things together....
Craftsmanship gets an F in my opinion. There are some welds around where the lift motors mount...the guy pulling the trigger on the MIG forgot to turn on the gas for 3/4 of the job. None of the cuts are deburred. In fact, one corner of the frame cut through the upholstery because there was a razor sharp chop saw burr along the edge of the steel.
The wiring is bad. Thankfully the only thing they wired were the motors and lights. I don't have to redo much but I'll have to redo it all in order to bring it up to our standards. The ground wire they ran for the lights in the top was about an inch short of where they wanted to run it so they spliced an extra inch into the wire instead of placing it differently or rerunning a longer wire. The dome light at the back of the van has about 20ft of extra wire just waded up in there...and it is 4 wire sizes bigger than the factory light wiring. Love the attention to detail.
What's sad is, including yours, this is the 5th recently done SMB top I've seen that in no way should have left their factory like it did. Y'all have paid some serious money for these tops, they should get their act together or stop doing them.
BTW... I've seen many CCV tops too and I couldn't say they've been flawless either.
