1994 Gulf Stream Scenic Cruiser

I'm considering the purchase of a 1994 Gulf Stream Scenic Cruiser, 230 hp Cummins, 6 speed Allison, with a diesel generator with 56,000 miles on the odometer. I would like to know if anyone has good or bad experiences with this model. I would like to tow my 5000# boat with it sometimes but I'm concerned the 5.9 B model Cummins may not have enough power, does anyone have experience towing with this model?

Thanks,

Mike

We sold the 94 SC and it was a good motorhome. We had several customers who had the 230 pushed to a 300. It cost $1800 hundred in about 2005. They can go higher than 300 horsepower, but most cummings mech. thought that was as high as you should go on a 5.9.

ga traveler,

Thanks for the reply, I appreciate the information. Hopefully the Cummins will do everything I need and I won't have to bump the horsepower up.

There are things you can do to the 5.9B that will get the HP up with minimum cost. If you decide you need more HP- install a pyrometer first.
Then go to the Dodge Diesel forums and read the posts especially the "stickys".
I got my old beast up to @ 320 HP and at 26,000 lbs total- she gets up the hills rather smartly.
Skip-96 Monaco 5.9B

Thumbs down Never again!!!

We owned a 1993 Gulf Stream with the small cummins diesel. We owned the coach for 5 years and had trouble with it for the entire time we owned it. If it wasn't the Gulf Steam portion of the unit it was the Spartan Chassis or the Cummins engine. Had to have it rebuilt on my nickel after it was out of warranty and went through at least 5 generators on the engine. We'd never consider buying another Gulf Stream and we're apparently on the only ones as they have anounced just a few days ago that they will no longer manufacture motorhomes.

PS--you may be able to increase the HP in the small cummins, however, it's the torque that really counts and although it can be increased to some degree, the gain will be bit more limited. To substantially increase the torque, additional cubic inches will be required ( i.e., a bigger engine!)

More HP @ the same RPM = More Torque..

Thanks for the replies; RSchleder, I'm sorry to hear you had so much trouble with your 93 Scenic Cruiser. It sounds like it was a lemon from the start.
I've had diesel engines in pickup trucks since 1984 and my knowledge of the 5.9 Cummins is it has been one of the most reliable engines for many years. That coupled with the Allison transmission makes the drive train very reliable so I'm not too worried about that. My main concern is the towing power of this motor home but it's not a deal breaker, I don't plan on any long trips towing my boat, they would mostly be within 75 miles of home and I could have my wife tow the boat with the truck if necessary.

sjholt; thanks for the information, I have a diesel shop close by I've used for years that would be happy to crank up the power on the 5.9 Cummins but they don't work cheap. I too believe the pyrometer is a necessity if you boost a diesel, I added a pyrometer, boost gauge, and oil temp gauge to the A pillar on my last Power stroke before I did any other mods on it, it really helps to know what's happening with the engine. It is amazing what a few modifications will do for adding power to a diesel.

Mike
