after adding a trailer hitch, and a set of add-a-leaf's to the rear to fix the ass end sag so she's all level now, i would like to consider a few upgrades.
1) full size spare - i've got the factory donut under there. I'm rolling on 235-75-15's, will that fit underneath without any mods? if so - whats a good donor wheel to search for. My bro has an old gen-1 (89) s10 blazer on steel wheels thats going to be scrapped... can i steal one of those? or is the bolt pattern and setback different than an 03 crew?
2) GOOD shocks - when i had the shocks serviced when i bought the truck, i asked the mechanic to sell me something decent. i'm at about 35k on them, and the rears will need attention before winter, based on what the guys who did the rear leafs advised me - which tells me the fronts probably arent in much better shape. i guess that shops definition of "decent" is different than mine

I want to get more than a year out of my next set of shocks if possible, so i'm willing to invest a bit more $$ to get there if i can. searching shows a lot of folks running bilstein, but the mechanic has advised me to go with Monroe OESpectrum - he thinks they're a superior ride for the $. when i start google searching.. the OESpectrums are about half the price of the bilsteins.
i'm not looking for off-road usage, i want a nice smooth highway/around town ride, and durability (longevity). however i do have to deal with michigan potholes and the crappy patching they do to "fix" them.
as always, advise is appreciated!
