Yeah that would be nice to have a 20 ft man, but I would be tempted to customize it, and that would be another year of running around and finding speakers, hydroturf, cutting holes, fiberglass splinters, and money here and there....that is what I 've done for the last year with my speedster.. Hard to think that pretty soon it will be time to store it for winter..have not had it out as much as i would have liked because of work also...
Anyway show some pics of the second battery install!!
