Vehicle Size Modifier

[Henchman99942]

Howdy.

Suppose I wanted a larger or smaller version of a specific type vehicle. Take a preexisting vehicle and increase or decrease it's size a bit. What effect would this have on it's stats? (ST/HP, Move, DR, weight, cost, etc...)

I am not looking for anything as complex a vehicle designing system. I just want to be able to tweek existing vehicle sizes to make new ones that have stats that are 'close enough'. I figure that I will not alter a given vehicle by more than one SM (which is a HUGE size difference if you are talking about doubling the longest dimension.)

And maybe a quick calculation for upping an existing vehicle from TL6 or TL7 to TL8/TL9/TL10. Like, what affect would advanced building materials have on it's weight and other stats, and so on.

Again. I am just looking for a fast fudged calculation... some modifier that I can plug into each of the listed vehicle statistics. There are enough vehicles out there in the various books to fulfill my immediate needs. I just need to be able to upgrade a TL 7 truck to a TL 9 utility vehicle, or a SM +5 TL 9 ATV into a SM+6 TL 9 ATV (These are just examples).

If anyone had already come up quick calculation numbers for this for their own game, but feels that it's scope is too limited or that it isn't accurate enough for use in a supplement, then that is probably exactly what I am looking for.

I really tried looking through the vehicle related threads going back to whenever. I didn't see anything that fitted with this.
