We are new members and are preparing to purchase our first RV with the intention of being fulltimers. We are seeking advice from those of you that have had experience with older Monaco Signature coaches. We are looking at and considering purchasing a 2003 Monaco Signature Commander 525. We have seen only photos so far but it appears to be of the quality we are looking for. It appears to be in good condition was well maintained by the grandparents (now deceased) that traveled extensively and spent winters in the south. This unit has 158K miles and the generator has 10,000 hours on it. Should those 2 facts scare us off? If anyone has owned a coach with the Cummins 525 (ISX 15 ?) we would love to hear your views about dependability, life expectancy etc. The generator is a 12.5 KW Onan, what is a reasonable life expectancy (max hours) on those?

10,000 hours on a 15 year old generator seems like a lot. That's like 13 hours per week all year. Assuming that the genny doesn't get run 2 hours a day every day of the year, that's some pretty heavy use. For comparison, I use mine lightly and in 23 years the Hobbs says 161.OTOH, 10,000 a year on the Cummins seems about right for a coach that heads south every year.

Have they done all of the scheduled maintenance on the coach and the generator and do they have documentation of the maintenance? When we needed to have things like the generator hoses replaced, it was a pretty expensive job, for example. Do they know what maintenance should be done and on what schedule?

I too would check into the genset hours. I have a 2001 Beaver and only have 1200 hours on my genset. As far as the coach I believe high quality. check out the expensive stuff like: tires, refrigerator, ac, water heater, heat, paint condition, etc. I can't comment on the engine but someone I am sure has the same and will chime in.Good Luck to you!You can find rv inspection people on google for Detroit!

Good questions! Grandparents who used it are deceased, daughter selling it says they maintained it regularly..don't know if she has records. Can anyone recommend either a qualified mechanic/inspector or reliable RV service facility that would perform a thorough inspection? Coach is located in the Detroit area.

It's high on milage and generator time, Id pass on that alone.

You guys need to move your posts to "Around the Campfire" :)

To the OP. I have just shy of 100,000 miles on mine and have had no problems or issues with the engine. The mileage would not bother me but I'd recheck the hours on the genset. There is a mistake there-just how big of one, I dunno. That coach would have been top of the line for Monaco and in 03 they were still considered above average as a company. I'd book a cheap air fare and go see it in person. If I liked it, then I'd spring for the inspection. Things to check for are maintenance records and date codes on the tires. If the coach was serviced regularly, the dealer/facility that did the service should have records if the daughter does not. The date codes, most likely will be on the INSIDE of the tires so dress accordingly. Also, any Cummins facility can give you a readout on the engine if you give them the engine code. Look for a tag on the passenger side of the engine compartment. Finally, call Monaco, now RVI, @ 1-800-509-3417 and see if they still have the build sheet on that coach. If they do, they'll fax or email it to you. That will have all the serial numbers of everything on the coach...best of luck..Dennis

Hopefully the daughter missed the decimal point and it’s only 1000 hours. While a diesel generator is good for 20,000+ hours that’s a lot of use on the rest of the rig. On IRV2 there are posts about the ISX dropping the #6 intake valve to the tune of $25,000+ in damage. Mainly ISX in RVs, not trucks and while the cause is unknown, it may be related to the EGR. If so, a 03 engine does not have EGR and may be how it’s made it to 158K as some with EGR did not make it to 36K miles.

As you can see below I’m a fan of the big Monaco’s and I would look for a 04-06 Executive with the Detroit 60 engine. Our Snowbird park mandates that we had to go to a 08 rig or newer and Monaco stopped having a Detroit as an option by then...I have a ISX 525.

The chassis is the same between Dynasty, Exe, and Sig with more bling and fewer non standard options in the Exe and Sig which have bigger engines.

IF maintained and good price, and you are pretty handy...go for it. Quality coach!!!

One must know the high milage on the engine is no worries, but the rest of the chassis is.
