One of my friends just got a motor home with a 8.1 & Alison tranny,I think its a 2004 model,not sure what brand,(Itasca maybe ?)--I was too busy gawking at the engine to care about what make it was--its on a P-30 chassis,has 4W disc brakes,I helped him bleed the brakes after installing a master cylinder on it,only part it needed...but the thing takes off like its a pickup truck,not a "bus" !..I think he said he paid 6K for it,only has 40,000 miles too..
He is a lucky SOB--last week he showed me the motor home,yesterday I ran into him at my friends shop,he came over and whips his phone out,shows me a picture of a '86 Corvette (C4 ?) that he got for trading a Kawasaki quad he bought off another friend of mine a few months ago,for $500!..
The Vette had sat 2 years,but all it needed was a new battery and some gas to fire it up,it needs tires and a tune up,etc,but overall I feel he stole it--has good oil pressure,is very clean underneath too,no rust!..
He saw it on Facebook Marketplace--the story goes the guy inherited the car from his grandfather and didn't want his 16 year old to have it for a "first car",and the kid wanted a quad or dirt bike anyways,not a car!..
As for towing,I'd still stick with a gas engine unless you plan on doing commercial towing on a regular basis--in that case a big rig is probably a better choice..
