2004 Land Yacht chassis

[jimandtere]

The 2004 brochure I have says that Airstream used the wider P30/32 chassis that was redesigned by Workhorse when Workhorse bought the truck/suv/motor home chassis division from GM in 1999. It also says that the engine was the GM Vortec 8100. But it doesn't say what transmission was used. I think it was GM's 4L85E. Hope someone could confirm this for me. Also, am I right that Airstream in that year had the wider track related to the Workhorse redesign of the P chassis?
Thanks

I think you are right about the transmission. I have the 2004 land yacht gas and I was told it had that transmission,
