Welcome to iRV2.
There were a couple of brake system recalls that , you'll need to confirm have been completed.
Knowing if the chassis has enough carrying capacity to suit your needs is important .
There should be an RV weight sticker in the coach ( picture below ) that lists the CCC ( Cargo Carrying Capacity ) or OCCC ( Occupant & CCC) , you need to find that # and be aware that if it's under 1,500/2,000 you will have trouble keeping the RV under the GVWR and tire carrying capacity .
The 8.1l GM V-8 and Allison 1000 series transmission is a great combination , but if the chassis is overloaded; poor handling will make for a white knuckle drive.
There is no standard placement for the weight sticker , you'll have to search for it.
Other info on the sticker will include , trailer tow capacity , important info for selecting a toad.
