Ok, to avoid further threadjacking, and in the hopes of getting some more pointers (especially from Claude and RedMenace,) here is the new "utility sidecar thread. Here is mine: <img src="http://lh3.ggpht.com/_5Pbryp6GOqI/SLGaDwrC-ZI/AAAAAAAADNQ/ibTtgmS7RCk/s400/rear_quarter.jpg" /> <img src="http://lh4.ggpht.com/_5Pbryp6GOqI/SLC2S2e0c6I/AAAAAAAADNA/roPgCORgwRY/s400/DSCF8503.JPG" />> It has an 11 gallon fuel tank under the hack seat, and the car is reconfigurable to haul stuff or passengers. There is a deep cell battery behind the fuel cell that powers the winch and the pump for the fuel cell. The battery is not connected to the bike - so if I use the pump or winch much, I have to hook the battery to a charger. I'd like to change a few things, and make it more useful. For instance - I'd like to have some weather proof storage. I think the existing fuel cell is horribly inefficient, as it takes a lot of space and requires a big ugly external pump to use it. Claude has pictures of a rig he built that is an older GS with a similar car, but it has storage where my fuel cell is and a spun aluminum fuel cell behind the seat. Another goal is to make it more comfortable to ride the car - maybe a deeper/lower seat with a little more foot room and a little bit of dish to it to provide some stability. Sorry for the wordiness.
