TC to Class C - anyone have a locking differential?

Thanks for the responses. I've looked at the Tigers before - maybe if I hit the lottery - will look at what Jayco has to offer. I don't plan any serious offroad travel with a motorhome - I have the Jeep and a dirtbike for that. The locking diff is just a convenience for off pavement (not off road) situations where that little bit of extra help might mean the difference between stuck and unstuck.
