Steve,
I see them on plumbing and electrical trucks all the time. Thanks for the anecdotes. Do you think it is just a 'bad idea' in general to try and transport stock this way? I was thinking about 3-6" PVC. Right now I am working on a small fence, and I want to pick up about 20 sections of 1/4" round stock.
We have an SUV that is mainly the family van type of vehicle. This is what I was planning to strap them to. Maybe I could just feed it inside the vehicle, and then not have to worry about the stock busting out of the PVC or getting the inside of the vehicle dirty, scratched or torn up...
I almost dropped about 2k for a diesel truck a while back, mainly for this very type of thing, but I just couldn't justify the cost of the solution
