It's a TBI truck, so chances are the thing will be fine once you get some fresh gas in it. I live in NH and I bought my '87 'burb in Colorado basically sight-unseen (I had my old man go pick it up for me). I replaced the smashed out rear glass, drove it around town for a day or two to make sure nothing was crazy wrong with it, then drove the 2100 miles home. I had a few hundred dollars in my pocket, barely enough for gas and some cheap food. Zero left over for repairs. Slept at a rest stop the first night. Got stuck in a blizzard the second night, found a friendly place to crash out luckily, friend of mine I hadn't seen in a long time. I was running on fumes by the time I made it home. Unless the engine or trans goes out, you can make it home with a clunky front end or a bad wheel bearing or sketchy brakes, just drive accordingly... Squares are pretty much bulletproof, and the one thing that plagues all old vehicles that have been sitting is the carb- which your '89 doesn't have! Go for it man, go have an adventure! Best of luck
