From what I understand about the IFS is it has to be cut off when removed so there's no way it'll "bolt on" to your dually. I would imagine that a SAS would be a much more simple, and probably cheaper soulution than trying to make IFS work under there.

^ Sort of.
You can unbolt most of the components. The question is, whether the 2wd IFS has the bolts for the differential, and if there is enough clearance between the lower part of the IFS subframe and the engine to allow for the diff to fit.
The other question is whether or not the 2wd IFS has the same width as the 4wd in the subframe where the lower a arms bolt up.
toyodually, I think your best bet is to crawl under the truck with a camera and shoot some pics of the 2wd IFS.

the only way to make it a 4x4 is to sas.unless you want to cut all of the ifs mounts off a 4x4 and weld them to your frame.would be way easier and cheaper to do the sas.

Hmm...Sounds like the 2wd IFS isn't compatible with the 4wd.
The only concern I'd have with doing the SAS then is the height. Simply judging from your avatar picture, you use the truck for working mostly. The SAS will significantly raise the truck, making that flat bed harder to load/unload from. If you are fine with that, then I think the SAS would be a good modification, especially if you are trying to drive across a lot of varried terrain.

it wouldnt bother me in the least being alittle taller, right now the bed sits roughly 3-4 inches lower then my waist. my tool box under the bed clears the ground by about 6-8 inches is all. and from what ive seen the SAS kits come in 3,4, and 5 inch lifts so that would be a great lift hieght in my book. my only worry is loosing my front dually wheels. they are the same all around unlike some of the motorhome duallys.
ive been looking for a 6 to 8 lug conversion like the 8 to 10 lug conversions for the big trucks but havent had much luck, so if anyone has some ideas let me know

2wd and 4wd IFS suspensions are COMPLETELY different. It would be a daunting and pointless task to put a 4wd IFS under there. Best bet is definetly a SAS and you can keep it mild, the kits they sell will come with lift springs that I think will be to much for your rig. I have the Trail-Gear 3" sas and 37's
For a stock 2wd rig that suspension would raise it around 8" or so over what you're at now as the 2wd sit like 4" lower to begin with than 4x4.. and the 3", 4", 5" numbers really mean 4-5, 5-6, and 6-7" of lift depending on the weight of the particular vehicle. and those numbers are the height gain over a STOCK 4x4
To keep it SAS and low, you can run 4x4 rear springs up front and play around with spring packs to get a more level (flat spring) to keep the front low.
I've seen under spring (but not using the J-pull arm) steering setups as opposed to hysteer which if you keep a low stance there wont be enough room for the arms to go above the spring packs so you'll want to go under.

Remember your gonna need more than just a sas kit. Your gonna need to swap in a 4wd tranny and transfer case, get a front drive shaft, hi steer kit, etc...
