I'm looking to get new shocks front and rear, a 4'x8' utility trailer and the hitch for my 2001 astro.
I need to get the bars for the hitch that mounts to the frame and whatever else goes along with it.

I was hoping someone here would have sugestions for all the trailer fixins I need.

I also do a lot of hauling in the van and was wondering if someone had advice as to what I could do to the suspesion to carry more, but still have a good ride when unloaded.

Oh Yeah ,what kind of wiper blades do you use the ones I got suck?

I put a class3/4 hitch on mine. It now can haul big things, and I have some more (45 lbs) of weight back there for winter. It just bolted on. I found GM already has the trailer wires installed. I found them on the passenger side door post, tucked up about window hieght. The color code is the standard trailer kit. You can find it thru the jack cover.
I have the standard suspension, which suits me fine.( and my 3500lb trailer) I friend recently had a spring shop put an extra leaf in for $250 Canadian
For shocks, I put in Monroe Seni-Trac. They ride better than stock, and handle well. Decent price too.
Hope this helps

Thanks for the info!
