They are built much heavier than a Jeep. Other than the 258 6 cylinder, the engines are rock solid, but the V8s are not known for gas mileage. I too, have had one of the 4 bangers. It was an excellent motor, and got 20mpg on the hiway with 4.10 gears. I think their electtronic ignitions were Prestolite, so parts can be a problem. The engines run forever, but they don't like to rev, cause they are medium duty truck engines, not pass car engines The later models used a 727 Torqueflight tranny, so they are almost bulletproof. Every Scout II I have looked at had a limited slip in the rear, from the factory. The bodies seem to be more prone to rust problems than Blazers. Personally, I think they are a good alternative to a Blazer, but parts can be an issue.
