1999 Monaco Executive 40DP Info

Hello In my long search I just found a 1999 monaco executive dp listed. Ive never seen one of these but I guessing its near the top of the line? has 450hp.
Has anyone had one of these? Info good or bad? What chassis would be under it ? If this is an ISM cummins is this one of the valve eating ones? At 40ft its really more than we need and dw tells me she wont drive it but Im drawn to the heavy chassis coaches after driving tour buses for awhile.
how clumsy will it be compared to maybe a 34-38 holiday rambler ambassador?
It doesnt have a slide and I can live with that but how bad will that affect resale if we want to upgrade in a year or so? Their asking 19k after starting higher. I know lots of questions but you guys are the experts...

PS I know a coach this large isnt an economy car but what mileage should you reasonably expect. 450HP!

Monaco custom built their own chassis called the Roadmaster chassis. It is very heavy duty and was based on an early Chrysler military vehicle design. If it's not a tag axle coach, it will have 8 air bags and 8 shocks. The Executive is the second from the top of the Monaco lineup. The Signature is the top model.

The Cummins ISM is not the engine that is having issues with the #6 intake valve, that is the 650hp ISX. The ISM 450 engine was an expensive option on a 1999 40' coach. The newer ISM engines after 2003 can have EGR (exhaust gas recirculation) issues, This early engine should be great.

I would not call the 40' model clumsy, but it will have a wider turning radius than a 36' coach. If you find a similar model with a tag axle it will turn as tight as a 36' coach because the wheelbase is shorter than a non tag 40' coach and the tag axle lifts.

Most of these big coaches (and many smaller ones) get 7-8mpg depending on how they are driven.

I'm not sure I would purchase this coach if you only intend to have it for 1 year. Most buyers are looking for at least one slide out. There are a few that do not want slides because of the complexity, but they are difficult to find when selling. Also, a 1999 coach will probably need repairs and updating and you can easily put a lot more money into it. As an example, batteries can be $1000, and tires are around $4000. It will help if you can do the repairs yourself.

Monaco does not list the 1999 model brochure, but you can download the 2000 which is very similar.

Hope this helps.

More info would be helpful. Is it a tag axle. Does it have slides??
The Executive is 2nd in line behind the Signature. Very Well built, top of the line. It will drive and handle great. The price seems reasonable depending on mileage and condition.

Like Vito.a said, tires can be expensive if needed. Depending on use/abuse it may or may need a lot of other repairs (although owning a RV is like owning a boat, another hull to put money into).

Not sure why your worried about price, a used diesel pickup will cost you more than 19K, there is still a lot of value in older coaches. Buy a new car and see what it's worth 4 years from now.

About a year-and-a-half ago I bought a 2002 Monaco Windsor 40pst with 59,000 miles and 3 slides. After I had to fix the fuel system for about $1000 it drives great but I have replaced all of the appliances except the washer dryer for about $3300. I had to replace the remote door locks, repair the air compressor and 12 air air leaks and backup camera and rebuild the automatic air leveling control pad and control board. The last four items would have been over $4000 to have done. Fortunatly, I have been an auto and heavy truck mechanic for 56 years so I have done all of these repairs so no labor is quoted here. I also replaced and upgraded the inverter and all of the batteries for about $4000 because they died. I repaired the drag link which Monaco wanted $2,000 for. It cost me $75 and some work. Be very sure to have the owner seller go through every and I do mean every item on the couch then explain how it works or doesn't. Have the batteries tested by an old school mechanic. The computerized testers do not work, especially to find weak cells. Wet cells have to be tested with a hydrometer which is seldom done anymore. New Age mechanics have not even heard of one . I'm getting my 2002 Monaco Windsor 40PST in top-notch shape to sell for $60,000 so that I can buy a new 26 foot Class C.

to fill in the holes, no it does not have a tag, nor a slide. Owner says it has new tires. I dont feel i need a slide but everyone now seems to have multiples and I worry that in a couple years if we go full time and want to upgrade this will be a hard sell. Looking for my first dp on a budget and thought this worth a look. Would this be beam type front axle?

No slides is a hard sale and will be harder in the future but there are lots of great deals on very high end motorhomes without slides.

Monaco's of that era were well built and the ISM 450 was a great engine.
