Welcome to the Stovebolt
It's hard to say if you paid to much or not. Are you happy with the deal? That's really all that matters.
As you probably already know you don't buy and trade big trucks to make money, you do it because it makes you happy. If the tires are all good and it runs and stops, plus has a clear title than $3500 could be a far price. The big money pit on these old trucks are tires ($1000+ for 6 tires) and brakes (about $1000 for all new parts with you installing).
Looking forward to seeing pictures!
