did you actually watch the video? its not 4 wheel steer its rear wheel steer. the only part of the frame is from the motor to the rear of the cab, after that its custom. as far as the tires, most agree that skinnier tires are better for snow because it allows you to sink in slightly giving your tread a better grip. YMMV of course.So they mounted tractor wheel/tires and 4 wheel steer on an old diesel dodge ram with what apears to be solid mounted axles. Then they drive it around in what looks like about a foot of snow.
The guy is a "master fabricator" and this is supposed to show off his skill? The truck is using the stock frame, no cage work that i can see, the only fabrication was the mounting the axles, running hydraulic lines to the rear, butcher the fenders to mount the tires, and possibly machining hub adapters to accept the tractor wheels. Other than that the truck apears to be bone stock...
Anyone with a MIG, a spare dodge, and a severe lack of taste/common sense could build that truck. You dont want skinny tires for snow, you want fat rubber you can air down for floatation. Extreamly tall wheels will let you 'stilt' through but thats an extreamly impractical and inefficient way of going about things. The rear steer is redundant and unessesary. And running any modern vehicle without suspension is retarded, especially if your a so called "master fabricator". Using a CNC machine to cut plate to mount axles is like using an exacto knife to cut your steak.
The frame is a stock dodge truck frame, possibly cropped after the rear axle. the cab is sitting on the frame as it would in a stock truck, nothing custom about it, unless sawz-alling a foot or two of frame off the back is "custom".did you actually watch the video? its not 4 wheel steer its rear wheel steer. the only part of the frame is from the motor to the rear of the cab, after that its custom. as far as the tires, most agree that skinnier tires are better for snow because it allows you to sink in slightly giving your tread a better grip.

oh, and i love the red green show.
So they cropped the frame to allow the tires to turn... another design compromise to allow the pointless tires to be fitted.dude, 24 seconds into the video, there is NO FRAME behind the cab. its a custom single rail that the rear axle is mounted to. actually, studded snow tires are thin tires not wide. look into any rally racing car that races on snow. as for the suspension, why does there need to be any for snow? there not rock climbing. it is designed for snow covered roads and fields. i seriously doubt its street legal.
