1995 BMC 37 Major Overweight Problem
Lee:
My 40' BMC was delivered with a lesser load range than that specifiedm on the placard. I upgraded to 'H' when the tires were replaced. The important thing is that my GVW is approximately 44,000# and I weigh out at about 39,500# totally loaded. I do need 120# in the fronts to meet the weight, but can run 100# on the drive and 85# on the tag. I totally disregard the BB suggested tire pressure. Go on the BMC group and ask the question. There are many 37' units on the list. I am the odd man out with a 40'. I believe the rear axle problem was corrected in '94. Someone will answer that on the other forum. I am currently roasting my stones near San Jose, so can't look at the coach for more info. Mike '97 BMC 40' Michael Brody, CEO Capital Progress, Inc. P.O.

1995 BMC 37 Major Overweight Problem
Neil,
Is the CCC rating, the GVRW of each Axel, minus the Actual Weight of each Axle.

1995 BMC 37 Major Overweight Problem
Hi Howard, thanks for writing. The official definition of CCC is the
difference from the GVWR less the actual weights of the four corners less the weight of a full tank of fuel, full fresh water, full propane, all factory installed options and a #154 allowance for each passenger on board. The number of passengers is based on the number of sleeping position and the quantity of seat belts present; hence the newest weight term SCWR which now appears on the RIVA dataplate. What capacity a remains after all of this is considered is CCC or Cargo Carrying Capacity. The old term NCC or Net Carrying Capacity was similar but had no allowance for the passengers on board and the tank of fresh water. There are many other terms used in the RV world such as empty weight and carrying capacity but none of them carry any validity by virtue of a industry standard. The weight remaining as you described it would be the CCC only if the coach was fully loaded with fuel, water, propane and a full compliment of passengers; then it would equal the CCC.

1995 BMC 37 Major Overweight Problem
Hi Lee,
Neil has provided excellent and comprehensive advice. Many BB's from the 90's thru our 2000LXi exceed the front axle rating by 700 to 1500 lbs with the slightest provocation, although the front axle is rated such that this amount of overweight condition is probably within the margin of error (if I recall correctly, our 2000LXi is 14,000 before an early recall and 15,000 after their fix and I have no idea of the axle rating of the '95). I'm not suggesting deliberate weight violation, simply that a lot of work is needed for the owner to get down to bare essentials and then to locate items carefully, just as Neil has suggested. A full-timer may not be able to achieve it without dropping the top speed dramatically, and upping the Load Rating and pressure of the tires.
