THOR #1605
2009 Mandalay Coach Presidio 360 42B

Wife and I are thinking about moving up to a larger used RV. The Mandalay 2009 Coach Presidio 360 42B (with Tag axle) has only 10500 miles with 1160 hrs on the generator, additionally it has been stored in closed storage when not in use.

Just a couple of questions, I fully expect to have small issues with it being 6 years old.

1) If you own one of the mandalay or similar size Thor Coaches have you been pleased overall with the RV?

- Whats been your biggest pro and biggest negative with the coach?

2) Have you found the Cummins ISC 360 engine to meet your expectations traveling thru mountainous areas and what have you found to be an average MPG?
- Does the ISC engine require DEF additives?

3) Does the AC and Heaters keep the coach cool (approximately 67 Degrees in both August and February in the South (La, MS, Fl)?

Any insight or opinion you can provide will be greatly appreciated.

Thanks in Advance

I had a new 2012 Tuscany 45LT with Cummings 450 in it. Plenty of power for climbing and lots of torque for pulling onto freeway. Mileage was around 6mpg with a 3400lb Honda in tow. Quality was okay maybe a 7 out of 10. I lived in Houston year round so with the three 13.5btu A/C's I could keep it around 68 degrees in the summer. My friends joked that you could hang meat inside because I keep it so cool. In the winter I used the heat pumps on the A/C's most of the time. Had to use gas furnace when temps drop below 32 degrees. I finally downsized because driving it was not enjoyable. I hated having to swing out into two lanes to make right hand turns without clipping the curb. I was a lot of hassle. My DEF tank was on passenger side so I couldn't fill it at the pumps unless you want to unhook to vehicle and then turn around and back through the truck stop. For me bigger was not better. I only keep it for 16 months.

Might the engine have been manufactured prior to the requirement for DEF? One reference I saw was the DEF requirement began in 2010, however I cannot say for sure.

Might be something to verify.
