Interesting modified M715

Came across this ad the other day. Don't know any more about it than the ad states.
"1968 Kaiser M715 Jeep PU Only 28K rust free miles. Fully customized w/a turbo-powered intercooled Hercules diesel eng. Too many updates to list. $12,500. Call Joe (Hampstead, NH) 603-329-5000"
I hope it is very nice for that money

I think MARS was the company that did Herc repowers. The repowers were very costly as shown by the asking price.

I think I have seen this truck at Weare NH. If its the same one, it was a very nice install job.
