Ah finally found this thread after a bit of searching.
Loads of helpful advice. Had an interesting time reading through it now that I'm considering a small searider, and I'm thinking of putting a jockey seat (possibly 2 seater) and console in.
If I manage to get hold of one, I'm considering putting a fuel tank in the jockey seat, so I reckon the "tophat" system would be the best route to take to allow access to the tank incase anything needs replacing. The padded part of the seat would be removable from the frame for refuelling purposes however.
Also wondering whether to build the console and seat as a combined thing, or 2 seperate entities. Any comments?
