Hi,
Im not sure what a comp crawler is, but if a Junfac Joker is one, then I already have one.
I bought Andy's joker off him a while back mainly because I wanted the two speed transmission to put in my CR01 Landcruiser.
I have had a mess about with the Joker, but I am not sure I get crawling, I love scalers, but out and out crawlers I am not too sure about. It might be down to the terrain I have access to, there are some stunning landscaped areas within ranches, its mostly sand but great to take the kids and a kit for a walk around.
If you see my other post in the 'creek crawl' thread, lets try that suggestion and see if I can be converted on the rocks at motor city.
Duane.
