I can't speak to others but I am building a fun family cruiser/camper rig and while I may never "need" the 4 wheel drive, it is good to know that it is there as well as while in the process of upgrading the drivetrain, better off upgrading to something that is better suited to todays standards with regards to safety and/or parts replacement.

Also this rig only has 127" wheelbase, so it really isn't that "big" overall. She'll just be a little hefty.

You might think about starting with a regular Suburban and maybe lifting and upgrading to 1 ton axles. I guess I'm not seeing the advantage of a C-50 frame with a Suburban body downgraded to a one ton. It's not like Suburban frames are really a weak point.

It is the grafting of a C50 medium duty front clip to the front of the Suburban body is the limiting factor. Doing that on a burb frame is rather difficult given the dimensions and shortening/fitment needed. There are quite a few start and stop threads out there on this very topic when they haven't completed the builds (mostly on trucks, but same premise for a burb).

I do get what you are saying, however my situation is rather unique. I have 1970 modified 4 door burb body on a clapped out frame (frame is useless). I have C50 chassis with 127" wheelbase (same as burb and long bed single cab) setup to run a Duramax and Allison combo. To get a C20 or Suburban chassis rigid enough to run a DMAX is a TON of work given that they will indeed bend or would need lots of boxing, not to mention clearance-ing to make fit.

Therefore running the ready made C50 chassis and downgrading the axles (since I won't be hauling gravel or produce) makes sense all around, especially given the price point I am starting at.

Sorry for the thread jacking Drewbee!

see here it is again that info would help from the start so we are not all grasping at ideas as to why you want to do it and will it work with limited info .

now that we know this it sounds like a solid plan for the drive line and why the use of a c-40 and up frame setup .
