What engine in the rigs? If either is the 600 or 650 HP ISX Cummins you might want to find out if it's ever had the new head, valves, turbo and programming update! Cost us over $22,000 (out of a $33,000+ bill to fix).

If you had not updated about the new records, and sitting for a period of time. Then I'd drive them both, and see how you liked them. As Steve mentioned, the Signature chassis is well respected. And I would not be worried from the bankruptcy timing in relation to the build date of the coach...

Really hard to go wrong with either one, as they're both top notch coaches. What you like, and condition (Documented condition.) is what this will come down to.

Best of luck to you,

There was only one Signature Series model with a number of lengths and floorplans. By '08 the shortest was just under 42' with most floorplans at 44'10". The standard engine was the Cummins ISX 525/1650. The ISX 600/1850 was an option and were often ordered. The 650/1850 engine in this twin cam design did have some issues with dropping a valve in cylinder #6. I don't know if this was a documented problem in the 600 hp version. I have not personally seen any reported but that is not definitive. I know of a Tiffin Zephyr with a blown engine in that time period and it was either a 600 or 650.

The Kingaire just had the Cummins ISX600 available I believe. The coaches were most likely very similar in equipment and amenities. I believe the MSRP was higher on the Kingaire but just a guess.

Both are superb motor coaches. I agree with the others, it will come down to condition and price of each coach. You could easily spend $20k+ bringing one of these coaches up to speed.

Also, as Mr. D said, do your research before purchasing a 650hp Cummins ISX.

Both great coaches as far as to quality. The only thing that would raise a red flag for me would be the Cummins engine. There is a thread in this forum I believe about the problems they have had with those big Cummins engines. I think I would do a lot of research on the engines before I would make such an investment.

Of course I'm partial to Monaco, but I would be all over that Signature after owning my Navigator. The quality of construction and if it has been shown some care, you'll be hard pressed to wear it out while you're enjoying the heck out of it. All of our coaches are going to require repairs or upgrades, the key is buying a quality coach up front that is worth putting the money in as you use it.
