Ymmv, but I towed 6-7klb trailers all over the country with the gmt400 half ton trucks, what you have. Still are on the top of my list of reliable bomb proof trucks.
You'll need to help the rear suspension, reccomend trailer brakes of course and the chassi will handle it fine. Power wise, no where near any of the new V8s but everyone used it in 1999 no problem. It'll struggle in the hills but otherwise capable chassi if you are prudent in your decisions.
Now if you load the Burb down with 4 screamin kids, 500lbs of luggage, trailer full of everything but another kitchen sink I'd say you don't have enough truck. Also towing heavy will not be friendly to a 250kmi old auto trans. Keep it cool!
Bottom line, you're right on the edge of what your vehicle will be happy towing.
Problem is, you don't want to sink a bunch of upgrades into your old whip just to sell it after the first trip.
I'd reccomend if you're an experienced wrench and experienced towing, go for it. If you're not that guy, I'd go bigger and newer for peace of mind and factor of safety.
Thanks. It seems my first instinct is right. We are experienced campers and could load light and make it work but I would rather have plenty of truck. I think I'm just too attached to that old thing and I was trying to talk myself out of trading it.
