Thank you everyone for the input. Your insight gives me a few things to think about.
Yes, similar trucks are posted for sale locally in an affordable price range. My future plans include moving on to a diesel truck, preferably from the 80's or 90's years.
This truck does have sentimental value because I have learned to do quite a few things on it that I didn't know how to do before. But I have never used it for what it was built for: off-roading and hauling. So my plan was to sell it off to someone who would actually use it for what it was built to do by the previous owner. But I don't want to sell it if it isn't structurally safe, which is why I asked my question.
Then again, maybe I can try my hand at body work and learn yet another thing on this truck...
Gonna do some browsing on the LMC Truck site.
While I continue to debate and ponder, other opinions and tips welcome. Thanks again!
