So it seems like 99% of aftermarket high tops/roofs are made of fiberglass. Some have wood supports molded in, some don't. It seems Fiberine and others offer the option of fiberglassing in wood inserts for rooftop solar panels/cargo racks, etc.
I recently saw this pic of a gutted ambulance high top, and really liked the added steel angle structure. I'm not sure how much strength this would really offer in a roll-over, but it's got to be better than just the fiberglass high top that's screwed/bolted to the existing van roof. I know the ambo boxes are rated for a roll-over, so I'm assuming this construction is for the same?
I've seen another aftermarket conversions with basically a mini roll-cage kind of construction/support in the high top area.
How much strength is really needed on these high tops? Does adding a tube structure offer enough benefits to offset the added weight high up?
