I had one many years ago. About 1975 as I recall. It worked and did what I needed but it was not a comfortable drive. Mainly because of the 1/2 ton under it.
However with your truck it would be a good fit.
For years I never saw one but DW and I were discussing this recently and noted that they are making a comeback. I suspect because of the 2500 and 2500 trucks becoming more comfortable.
