2000 Dynasty Bad weight distribution

[Timaz]

I had smart weight done to my coach and it came out very bad. My only guess is the airbags were out of whack. any other thoughts. I will be redoing it next month and I will put in my jack stands just to have it on the scales and confirm my thoughts. Any other reason this could be so far out??? See results.

Front Back
7850 8575

3900 14015

HOLY WOW!! I'm not sure that I understand your numbers as to which corner is which. Are you saying the left and right on the front are 7,850 and 3,900 respectively and the left and right on the rear are 8,575 and 14,015 respectively? That would add up to a little under 11,750 on the front and about 22,590 on the rear. It would add up to 16,425 on the left and 17,915 on the right. The total of 34,340 pounds sounds about right. But that puts 21,865 pounds on one diagonal and only 12,475 pounds on the other.

Your numbers, if they are true, and if I've correctly guessed at which corner is which, suggest that you must have one heck of a huge twisting force on the frame and box of your coach! And I would expect it to be a bit on the hard side to drive on anything but a straight and level highway. You are very wise to pursue it. Either the weighing was done incorrectly or yes, something is seriously amiss with the air control and distribution to your air bags.

Also, just out of curiosity, do you know the axle ratings for your steer axle and your drive axle? Your coach seems to be a bit rear-heavy. I don't know, though, as we have a tag and that probably changes the choices for drive axle load requirements. I think my drive axle is rated at 20,000 pounds.

Wow! Keep us posted.

Tim -- There will be some RV`ers that I know & will be in the area this week - They are very mechanical & know the Monaco product -- They are part of the Quartzsite Gang -- Perhaps they could meet you here at my place here in Gilbert for a look see -- Bill Willard

Front is rated at 13000 and the rear at 23000

That would be great Bill. I will be in Glendale this weekend but after...or this Sunday afternoon would be perfect. :-)

Airbags won't cause that kind of discrepancy. Go have it reweighed and don't leave until more accurate results. Slight differences yes, but not like those. Good luck Don

[barmcd]

That's so out of wack I don't think it could be accurate.

[Timaz]

The travel mode doesn't work on it's own. I have to manually raise the coach. I'm thinking the two diagonal corners that are heavy have the airbags up too much carrying too much weight.

Do you by chance have a rocker switch or a push button switch either on your left console, on your dash, or perhaps mounted inside of your front run box that says something about HWH RESET? It may have a red button or light on it. Ours does, and ours in mounted in the front run box on our '06 Dynasty.

If you have that, turn your key on and use that button to try a RESET on your HWH system. Then see if your TRAVEL MODE will work. As you know, you will need to have your air relatively full and your key ON (I would do it with the engine running to make sure there aren't any permissive devices keeping it from doing what you are asking) for it to come up to ride height when you press TRAVEL MODE.

Keep us posted. I'm in agreement with several of the comments that it is not likely that air bag inflation by the system is the issue, but when you say what you did about going to ride height manually, you may have hit on the crux of the problem. Try the reset and then let us know.

Try this link, Tim. It has a great troubleshooting section that begins on page 5.

Your crazy numbers actually might be true. In my 7:49 AM reply above, I made some assumptions about the numbers you posted and which ends/sides/corners they were for, and if my assumptions were right, your total front to rear total weights look reasonable, and your total left to right numbers look reasonable. Also, based on your reply, your total axle loads look good. Your individual wheel bearing, hub and suspension loads could be dangerously beyond design, however. The twist that those numbers would cause really is a serious concern from both a coach torsional load standpoint and from a safety in driving standpoint.

It hadn't tumbled to my head that your HWH could be the issue, but your comment about "travel mode" not working got my attention, finally.

See if you can't download this manual and work thru the troubleshooting section.

Looking forward to hearing back from you.

My panel does not look like this one. I will post a picture tonight after work.

Here is a picture of my HWH air leveler control panel.

Interesting, Tim. Similar to ours, but different is true. Check this out.

Here is the link to the main HWH website. https://www.hwhcorp.com

Here is a page on the HWH website that suggests that you have the 680 Series in your coach. https://www.hwhcorp.com/ml17785_01_nom_pr_lesy.html

Here is what might be the right manual for your coach. https://www.hwhcorp.com/ml19048.pdf

Good luck, Tim!

Thank you, this helps a lot. Points me in the right direction.
