.... pop-top design??? :drool: Tell us more!!
I'm not going to let the whole cat out of the bag yet so no pictures until I get a little farther.
Here's what I will say about my upcoming pop-top design:
-It's looking like I'm going to go with a dual-acting, single motor actuator design. I had been going down the path of two independent actuators but it drives the cost and complexity up a bit. Not to mention there are some pitfalls to a two actuator design should there be any failures. I'm working with another engineer to verify that all of the members and mounting frame can handle the loads and we're designing in appropriate safety factors. All of the pivot points for the members are in double sheer too.
-The mechanism is a very open design so the cutout in the roof will be 50+" wide x 110+" long. (these numbers may change slightly as I get farther into the detailing). RB vans will use the same hole size and mechanism as EB vans, the only difference will be the EB top will extend farther back.
-The top itself will likely be aluminum. The tricky part is making an easy design to manufacture while looking sleek. I have visions of an integrated roof rack too.
-When I get some final dimensions, I'll engage with some local canvas/tent making vendors to discuss material options and design. I don't expect to deviate far from the 'windows/screens on all sides' design that the other guys have.
-It's gonna be trick but the goal is to keep it in line with the prices of the other vendors.
