Beaver Marquis or Monaco Signature

I have been looking at a 2002 Beaver Marquis and Signatures from 2001 to 2006. Currently I have a 2000 Monaco Dynasty double slide 350 HP cummins.
This Beaver is exceptionally classy inside with a Car 505 HP. My question is pound and torque to weight ratio. 350 is 94 lb to1 hp , torque is 31 lb to 1 ft lb while the 505 cat is 76 to 1 hp and 24 to 1 ft lb toque. This Beaver weight in at 37200 which seems like it should be quite a hot rod which translates into pretty decent fuel millage if you run at a reasonable speed. Any comments would be appreciated.

This is just my observation and from what I have read on the Beaver forum, but it appears that the more HP the more fuel it uses. My 350 gets around 9.5 mpg and the guys with the 500 HP get around 5.5 mpg or less.

These coaches are designed for reasonable performance and economy within the reality of the GCWR that they must propel down the road. The coach with the Cat C12 or C13 is in a coach with a GCWR of over 55,000 pounds. The Cat C7 is going to be in a coach 10-15,000 pounds lighter. There will be a difference in the economy that both coaches are capable of returning. That being said, I'm guessing that the Milage difference between the two will typically be much less than these two extremes.

Wow, your mileage is stunning. I had the same coach, 2003 Beaver Monterey, for 10 years and I got 6.5-7 mpg while towing, 7-7.5 if not towing. You must drive slowly or something.

mileage

If mileage concerns you, you need to get the smallest diesel engine available and drive slowly. If mileage doesn't concern you I would get a DD60 or CAT and live with the 1-3 mpg less, drive slower and know that you have the hp/tq if needed. I once had another item explained to me this way and thats if you were going to drive to California would you go in a Pinto or a Cadillac, their both going to get you there now you make the choice.

I get the if you worry about millage you should not buy the coach. I understand that if you are pulling half the world behind you the millage may not be great but if you are not fully loaded pulling 37000 with 505 hp vs 31000 lb with 350 hp should not your millage be the same or better? Back to my origional question of monaco sig vs beaver marquis.

My wife and I have lived full time in our '03 Sig with a Cummins ISM 500/Allison 4000 drive train. The coach has just over 100k on the clock. In flat to rolling interstate driving with a speed target of 62, my Milage averages plus or minus 8 mpg.

Don't know anything about the Beaver but I do have a Monaco Exec that has all the options of the Signature with DD60 and a lot of people on here have the Exec or Sig and are really happy so with that being said I would opt again for a Exec or Sig my 2 cents
