I don't know how much weight the top added to the van. Next time I go to the landfill or by an empty truck scale I'll weigh it and post the results. It feels the same on the highway so not much.
I haven't been able to do any work to the van lately because I had a bad crash on my road bike about a month ago. I don't remember exactly what happened but I know I hit a speed bump, went over the handlebars and slammed the pavement with the right side of my face. I was taken to the hospital in an ambulance. I spent three days there before I could go home. I suffered a pretty bad concussion, cracked my orbital, broke my clavicle into three pieces and cracked one rib. I'm doing alright now but the first few weeks were pretty bad. That head injury messed me up. I couldn't think straight, speak clearly or read anything.
I'm glad that's over. My brain is working fine now but I'm not doing much work on the van until my clavicle is back together.
Not that it mattered anyway because of the complete lack of snow this year, but this ended my snowboard season after only one day on the mountain. Oh well, could have been much worse, right?
Before the crash I installed some carbon fiber seat heaters I got from eBay between the factory seat upholstery and the covering covers. I still need to wire up the power to the switch, I have a good plan to keep it looking really factory and use the factory fuse block. I'll post up some photos when it's done.
