Kinda looking to tube up a truck.  Might use my 99 blazer but lots of problems with this.
a) its 2wheel drive
2) the engine isnt the greatest (its the 4.3 vortec but its got some probs.)
3) its ifs.
the list goes on

 
Living in the FL we dont have many rocks to climb but the cage effect looks bad ass and I'm sure i can find some utility for it in our rolling mole hills and mud. 

Any suggestions on how to start the conversion from 4x2 to 4x4?  I know I'm going to need to get some more transportation considering that the Blazer is my daily driver. 
Should I not bother with the 2 to 4 conversion and just find an s-10 blazer thats already 4x4?  I wanna stay with the midsized SUV.

Thinking about running dual transfers (like the Ultimate Taco) looking to get at least 33's on it 35's if possible. 
Any suggestions are welcome (cough fred cough). 

Other people might tell you it'd be too much of a headache to make it a 4x4, I'm guessing it'll cost up to and maybe over $3000 to get it done right. I heard most 4x4 owners rarely put it in 4wd, even on most trails; so a 2wd can go most places a 4x4 can go. If I was to modify a 2wd Blazer for 'wheelin but still commute, I'd probably want a way to lock the rear dif (air or auto locker), all-terrain tires, an onboard compressor or charged bottle (like a scuba tank) so I could "air-down" for the trail and refill when done, maybe some lower dif gears and possibly a mild to wild suspension lift. (6" plus) You'd probably like running tires at lower pressure on the trail. I have trails I take a mountain bike on near my home and there's a section where a few hundred feet is deep loose gravel. Anyways, normally going through this section is a pain in the ass. (I normally ran 25-30 psi in my tires) I aired down to 15 psi and the ride was amazing. My bike hardly slowed down at all when it hit the deep gravel and I seem to float on top of it instead of plowing it. It rode like a dream. For an automobile, I don't think I'd ever want to 'wheel with pressures at or above 35 psi. If the motor's a little sick, do a tune up before you do much 'wheelin. I had friends blow stock motors in seemingly good condition trying to get unstuck in mud.
