Title: Sagging rear end
Post by: campergates on April 13, 2017, 07:34:34 am
Not mine but the 2351's.  I have a rack on the hitch to carry my bike and kayak and there are times when leaving or entering a parking lot that it will drag.  Has anyone successfully done anything to raise the rear of your PC?  Thanks

Possibly install a curved receiver bar to elevate the cargo rack.  Our cargo carrier is always loaded with my "cripple cart", Baby Q, and a screen tent.  Here is the one we bought and it came with the upcurved hitch bar. so far no sagging issues.  https://smile.amazon.com/gp/product/B001G4Z5J0/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1   Pics added.   :)(:

We own a 2016 2351 on a E-450 chassis and have no sag issues. That said, we did own a Born Free that was over weight. I had parabolic springs installed which solved the issue and made the ride better. But expensive. Over nine hundred bucks installed.

It seems that every PC built on an E350 chassis sag a little, some models more than others.  Our older less load-capable 2007 E350 chassis has a slight sag as you can see in the picture below.  Our rig has no slide out so that reduced weight reduces the sag by some amount.  The picture was taken during one of our trips with a normal on-trip load.  It's not much of a sag but it's there.

I had considered installing those affordable Firestone air bags where you add air like in a tire to get a few inches of lift.  A few inches is all I would need to get the rig perfectly level.  I never did get the air bags because I feared the ride would get more harsh, and in my case, the a/c unit might hit the top of our garage door opening if I forget to let the air out when back at home.  The softer ride is more important to me than lifting the rear end to get the rig perfectly level.

I really should place our PC on a level parking pad and compare that to the floor inside the rig.  It would be interesting to note any differences.  I would do it in our garage but the garage floor is sloped to drain water towards the garage door.

We had an extra leaf added to the rear suspension instead of air bags. It was much less expensive than the quoted price for air bags and the impact on ride quality was  positive. It raised the rear about  an inch and a half.

Your comment is very interesting.  If I could be assured our a/c unit won't contact the garage door frame, I would look into it.  But when I park the motor home with the a/c unit under the opening, it looks like about a 1.5" gap.

Thanks bhgareau for sharing that.

I haven't used these and don't know if it stresses portions of leafs in ways they shouldn't be stressed, but the concept is intriguing: http://www.torklift.com/index.php/products/suspension/stableload
