Not popular enough with the crowd that’s into the old trucks. Plus sellers think they have a gold mine with a LRE. Problem selling a LRE is you have to find the guy who wants one. With cars I’d I shut is looking for a b-body he may end up in a a-body if onecatchrs his eye. a LRE is a late 70’s truck and that’s how it’s viewed. Not viewed as a muscle car so it’s overlooked a lot.
