Longer term primer
I would like to know if there is a primer that I can use but does not have a short window to paint over. I am talking a couple of months. I plan on doing the body work on weekends, driving the truck during the week. Any suggestions?

This is a tall order. The primers that I am aware of are all porous. It might be that Epoxy Primer would work except for two things; it has to go over treated bare metal and it has to be sanded to before topping over it if it is past about two weeks.
If you are going to bare metal anyway, then it might work. Most any other primer is porous enough that it will trap moisture underneath making for a short lived paint job.
All this said, most of my knowledge is with older products. With the catalyzed products of today, maybe there is a modern magic bullet for you.

I'll 2nd that Epoxy primer is the way to go if you want to protect your work until you can paint it. That is what I'm doing, just make sure you clean the old epoxy primer surface and then sand the surface and then clean again, before you top coat over the epoxy.

I worked at a Corvette restoration shop and we used Lesonal black epoxy primer for the chassis. It was left un-coated since the satin finish was accepted by judges as correct for thise cars.
Some of those cars were done 10-15 years ago and still look great. The epoxy primers need to be sanded if left more than a few days.

Is this what you are referring to?

I expect to re-sand/re-prime the entire truck when it comes time to actually paint it, but I know with the time I have available it will be awhile before I will get it ready for that. No rust, a few small dings, and some holes on the front fender. The truck is a 73, but the fender came from a 76 with different trim. I am not sure how I will try and fill them, weld/grind? The final color will be a gloss black.

You REALLY need to MIG those holes up. Brazing introduces dissimilar metals ultimately leading to corrosion, plastics will shrink and crack out. MIGing them with gas shielding is quick and easy. If you don't have a MIG welder, you probably know someone who does. If you know no one, find a welding shop. It will be quick and easy, thus it should not be expensive.

Lesonal primer
To sons73, yes, thats the stuff.
There is also a self etching primer for severly corroded metal. The self etching primer contains zinc hydrate, so use caution.
Be sure to use a proper resperator or fresh air mask, this stuff is nasty.
