[Tf175]

That coach looks almost identical to our '86 . The vin is on the wall under the console at driver's left . When I bought #89 over a year ago it's condition was daunting,  but it fired right up , ran well and drove like a dream . But , it had new house batteries and all new tires . I felt it was pretty much road worthy , having recently made a 1300 mile trip . After much work we have now made three trips to the races pulling our 28ft trailer and are really enjoying the coach . People say it's the coolest thing at the track , peeling clear coat and all .
In my humble opinion,  if the green coach fires up , builds air and stands up on the suspension,  goes into gear ,etc , might be worth further investigation.  Those cracked tires though..
Good luck .

What kind of mileage do you get pulling the trailer?  What does the trailer weigh?

Trailer loaded is around 10k , haven't weighed it lately . I don't have an accurate fuel mileage as yet , tanks are linked so generator consumption is included . On a 1300 mile trip in July , genny ran three days straight , we saw 5.2 mpg , tried to maintain 60 /62 mpg. Trip to finals the other weekend , just under 800 miles , four days of gen , 4.6 mpg , 67 /70 mph . Generator is 12.5 kw Kohler with Perkins 4 cyl.
