That is a fine '71 for sure.Usually I've seen special paint on a fleet vehicle but yours sure was no company truck,I'd think.I see your truck (and maybe cheyenne shortstep's) as maybe being ordered by some dealer who was into setting some sweet special rides on his lot.Both seem to be something special.Silver w/blue interior is a stand out combo,especially for a truck.I see it was solid paint since a two-tone would have had the paint divider at the bottom roofline.Cool truck! I'd want it back to original,yet unless it's single stage it's updated.I might be tempted to go with Cortez Silver,too.It may not be exact,but a period correct color and it's not like it's a production color that everybody would know was off.It all depends on how original you want.You don't see stuff like this everyday.
I just noticed it also had camper mirrors.You don't usually see those on a truck like that.May have been ordered as a tow vehicle...for a race car?I think I'm fantasizing now
