Best older Dodge pickup for daily use?

For what I'm in need of mostly, the /6 or 318 2WD will suit me. I found an '87 D150 near me, long bed w/318 auto (don't know yet if 3 spd or 4 spd OD). Has over 100k miles, looks fairly rust free but won't know for sure until I see it in person. I believe this is the last year or second to last year for carbureted. Which is probably ok, I was thinking I wanted 89-93 EFI but if those have issues it could get expensive.

The catch is it has overheating issues of which the seller states it needs a heater core. From what I know these are usually buried in the dash and a real b*tch to get to on most vehicles. But how hard on an '87 Dodge truck? A new core costs $50 at advance auto so cost is not an issue.

Update: the truck is sold already. wish people would take their ads down then. Probably shouldn't be surprised, it was only $2k and looked pretty clean. That's something for a 27 year old truck in Ohio.
