Wheelbase?

[Bulldog]

I know this is opening up a can of worms. Everyone has their opinion of what they like best. I would like to hear pro's and con's of going short, medium, or long. As everyone knows, I am getting a small collection of Chevy/GMC trucks. I am planning on building a totally dedicated wheeler that is still street legal (not only legal, but handles decently also). I want to be able to drive to the trail, may be here locally or a trip down towards Anchorage. Trails will be the trails we all run as a club. Truck will have 38.5" to 42" tires. I want to make a decision before I put too much time and money into my current wheeler.

First off I will throw out some numbers.
Jeep TJ 93.4" wheelbase, 154.9 overall length (LWB version: 103.4" WB, 171" OAL)
Blazer 106.5" wheelbase, 184.8 overall length
SWB Truck 117.5" wheelbase, 191.3" overall length
LWB Truck 131.5" wheelbase, 212" overall length

I currently wheel a LWB truck, but feel I have some difficulty going over some obstacles because I get high centered with the long wheelbase. I currently wheel 33" tires, but have some 38.5" so this might help. I haven't had any problems on the trail because of length, but turning around could be difficult. The lower loop at Banner required a 3 point turn on one corner, but I think a lot of vehicles had to also.

I currently drive a SWB truck, but haven't wheeled it yet because I lack tow points and traction aids. The truck seems "bouncy" going down the road. I may have to experiment with shocks, but my LWB truck rides better down the road. I don't know how much of my ride could be related to the short wheelbase or the lift. I've also hear a lot of rock crawlers saying that 120" is the ideal wheelbase. The SWB truck is just under 120".

I am tempted to try a Blazer because it's shorter than the SWB, but don't want to sacrifice too much ride. Blazer vs. SWB truck is 11" shorter, this would be beneficial going over obstacles. What could the downside be of this though?

I currently have 3 LWB trucks, 1 LWB crew cab, 1 SWB truck, and 1 LWB 1-ton frame. I trying to decide:
1.) Go ahead and wheel my LWB CUCV.
2.) Buy a Blazer (I have lots of goodies I can use to build it)
3.) Cut my 1-ton LWB frame down to Blazer WB length and make a truggy out of it.
4.) Cut my LWB crew-cab frame down to SWB regular cab wheelbase and make a truggy out of it.
5.) All of the above :p
I'm sure I have enough parts to build two decent rigs, but don't have the free time to maintain two; plus I can only drive one rig at a time.

FWIW, I'm going to go minimal on the suspension lift to clear 42" tires and keep a low center of gravity. Plenty of fender trimming going on here. I'm probaby also going to bob and narrow the truck in both the front and rear.
