Here's my $0.02
4wd or 2wd?
Assuming it really is mint and nicely optioned with 95% of those options working; 4wd $6-8k, 2wd $3-5k (CAD)
I'd be careful about claiming rust free status. I've yet to see anything in canada that qualifies as rust free. If there are any defects on the truck, be sure to show them in the ad rather than hide them. Someone looking for a cherry will be willing to wait for the right one. If he thinks you're hiding something, you can expect lost interest or at best, a low-baller. As for the low miles, look at the brake pedal. If it's worn through, then the odometer has most certainly rolled over at least once.
This might seem extreme, but look at this ad for an example:

Photos show most everything on the car that a prospective buyer would be interested in. Note the good lighting, the controlled backdrop and the attention to detail on everything from the fenders to the gauges. It's pure eye candy. I would even remove the camper and set it aside because it doesn't look clean compared to the truck. An empty truck shows potential, while a loaded truck shows a possible "project".
If you want to pitch the truck as a classic that is collector plates ready, then you need to make it look like one. Clean it up very well. Clean up the interior AND the engine bay, then include clear photos. Show photos of all the rust prone areas to prove how clean they are. Don't try to hide any flaws because someone looking for an 80-86 ford will know exactly where to look. It might seem like a lot of work, but if you can get an extra $1000 when you sell it, would your extra time not be worth it?
Right now, prices on these trucks are still bottomed out, but cherry original ones are starting to move. I've been really surprised to see some on the lower mainland in the 7-8k range in the last few years. And they usually don't stay up for long. Other ads that have poor angles and few photos can sometimes spend more than a year on craigslist.
It would have been better if the truck was 4wd, but even a 2wd that is very clean could fetch up to $5000. Unfortunately, there are still plenty of decent (not perfect) IDI's to choose from that are 2wd. They're just so terrible on snow that many really did get parked in the winter and spared the salt. Not VERY many, but certainly more than the 4wds.
