New Bambis don't have springs. There are no mods that I know of that will adjust the torsen axles.
I'll measure mine when I see it next and let you know the total length and ground clearance.
A bit off topic, but if you are intersted in a Bambi, I may be trading mine in the late fall, early winter. If I do, I would consider selling it at a price less than is being asked for on most of the on rv ads. Best part is that the unit still is under warranty for a year from the middle of this coming February. The only real soild issue with it right now is that the furnace will not light. It needs a new or adjustment to the ignitor. There are also a few fit and finish issues, but nothing above or beyond what has been posted about the new ones being sold in 2004. I care for the unit like it was a child. Think I've washed and Walberized it at least 4 times since March.
No dings, dents, etc. Very clean used about 6 times with less than 2,000 miles on the coach.
PM me off line if you're interested.
