How hard is it to find a 4x4? I have only seen a few.
Are they really unicorns?
How much of a price increase compared to similar 2wd?

depends on what exactly you're looking for. the chevy/ford short buses like mine are converted fairly easily since they are just vans with bus conversions done to them. the thomas style buses like posted above are rare but are doable. hardest part would be finding a front 4x4 axle that would fit under it. using a divorce transfer case would eliminate the need for a 4x4 style transmission. then you would just be left with fabing up shift linkage and having someone make custom length drive shafts.
You left out the changes to steering, brakes, and clearance for the front diff and driveshaft.
In my case, (for example) I have a freightliner truck chassis so I'd start by looking at freightliner trucks of the same size class and era and see if freightliner ever offered those trucks with 4x4 -- those parts will be the most easily adaptable...
If you ever want to lift your FL let me know. I can give you my vin. Mines 2wd but did come with 5" lift blocks. I'm really digging the ride height.

Step one -- replace the 'treadless' hwy drive tires with an all terrain tire.
If that doesn't solve the embarrassment of getting stuck in wet leaves
Step two -- I'll get a used detroit locker. (I don't think a limited slip (clutch pack) locker is a good idea for something this heavy...)
Step three -- get a different vehicle -- why be shoving the square peg in the round hole...?![]()
Mostly agreed -- that's why I said look for the same chassis as your bus in it's 4x4 truck form so all the front end parts easily move over and fit.my experience is limited to the cutaways but other then lengthening the drag link and track bar i couldn't really see what all would need changed in the steering. i also would assume you would only need to get longer brake lines if you lifted it for clearance but nothing really modified brake wise. But again i never messed with a full size one.
in my experience people over complicate things and tell people it cost 14k to convert something to 4x4 when it can be done for less then 2k. If you're good with a welder and have basic mechanic skills its not that hard to pull off.
Since you say full size tires won't fit I'd start with making them fit.
Or- find a bus that's not lowrider?
You said you don't think 10 or 11R's would fit and that the lowpros you have now are "stuffed" in the wheel wells. Or am I confusing you with someone else? Cause that can happen!
Someone else...
But since we're 'talking';
My bus has Michelin XDE M/S drive tires on it now -- but they are worn close to the legal limit -- but they also say (molded onto the sidewall) that they're regroovable -- is this a real thing? Do I wanna try that with 4 tires? It would be nice to save $1000 that's for sure!!!
