Nine more feet of frame...I'm curious myself as to how the weight distribution works out.


IF any frame will need to be added to the original, it would be less than 2 feet, and only to support the receiver hitch and filled in back end. Placing the LOX tanks in the front made it look better, but also more functional, but shifts about 500 gallons (4000#) of weight rearward. Load weight will now be about 65/35, if not 60/40 front to back. With the bridge formula laws, max weight on any axle is 20,000 pounds. My wheel base will allow a max of 47,000# total as is, so I can easily set up as a pusher or tag and be legal. Tare weight is expected to be <12,000#.
