Can you add penthouse motor to manual pop top?

Just wondering if you can add a motor to a SMB penthouse top to a SMB top that's currently a manual pop up?

I'm almost certain that Sportsmobile (the company) used to retrofit them. Someone here will remember.....or know.

I think it would involve some fabrication though, which could be huge or a walk in the park depending on your skill level.

I did send them a message, just waiting for a response. Figured someone here would know for sure.

Fabrication won’t be an issue. I can make anything work, just wondering if there’s a kit or if maybe it’s an all DIY sort of thing.

I’d love to see what motor is used and what the linkages look like.

I think you can find pictures on the forum if you poke around some. As I recall they're using two linear actuators, pushing horizontally on the bottom end of the scissor lift tubes. One flaw in this system seems to be that if a hook catches or anything else restrains the top, the tubing bends pretty easily.

That's just my recollection though -- I have a manual top.

I've also seen non-SMB systems that used an airbag at each corner to do the lifting, which is an interesting idea.

Don’t know if they still carry it, but I believe at one time Aluminess offered an air lift to help raise manual tops (believe you needed to hook an air compressor to it). If I recall correctly it was a single pole you positioned between the floor and middle of your top.

I had SMB Texas retrofit my top with lift motors. Plan on it taking 2 days of their time - if they get it done faster great, but if they have problems it will take 2 days. Get a hotel room, get your stuff out of the van, then drop it off.

And of course, be prepared to wait for a time slot to open - ALL RV places are tremendously busy right now.

SMB Penthouse Top Motor ?

Greetings -- I recently checked into the price of a SMB Penthouse top motor - quoted at $ 300 bucks at SMB North. Anybody know where the motor is actually mounted and where to gain access ? I don't need one as mine is working - but it is 2002 vintage. Just want to be ready "if."

I got a response from Sportsmobile: "If it’s a Sprinter it might be possible, if it is an E-Series then no its not."

It is an E-series van by the way.

That would be great if someone could post some motor photos to include mount location and linkages. If it's not too much to ask.

There are a bunch of SMB top pictures in my album without all of the covers in place.
