Tag axle on 2000 Dolphin

I've got a 2000 National Dolphin with a tag axle. When returning from our trip the unt is leaning on the right side. Found a right shock mount broken on the tag axle and will repair that today. However I doubt that alone is causing the unit to lean. Will check leaf spring suspension when shock support is repaired but are there any other ideas? Also is there a website for National parts for this unit. Thank you

You have all the posibilities covered. Like any other RV Mfg, about the only thing brand specific is the fiberglass body. You'll have to know the chassis mfg to get parts for it. Do you know what chassis you have?

I believe that you will find that the tag axel was added to the chassis by National RV and was not OEM from Ford. I may be wrong, but I don't believe that anyone made a gas chassis with an OEM tag axel.

Tag Axle

I have a 98 Tropical with a tag axle on a Ford F53. The tag axle was added by National and is made by MorRyde suspension with the axle made by Dexter Axle. There is a National group on Yahoo groups. Hope this helps.

I had the same problem with our 1998 Dolphin, we broke one of the rubber springs on the tag axel. I called Mor-ride direct and told them what we had and they shipped the parts straight to me to repair the tag axel. We were back on the road in a week.

Wow...... Small world .

I own a 2000 Dolphin that leaned to the passenger side, and had a broken tag shock mount on that side .
I have'nt taken a four corner weight yet, but I susspect the rig is heavier on that side. I recently installed air bags on the rear, run about double the air pressure on the passenger side as the drivers side, and have pretty much eliminated the lean.
The shock mount was likely broken by the previous owner taking a right turn too tight, and striking the curb . When I bought the coach, I saw a dent on the dually wheel cover, but eveything underneath 'looked' fine. Second year I owned it, decided to replace all shocks. Went to remove that shock and found it was just being held upright by the lower mount ! Had the bracket welded to the frame, and so far, so good.
No, repairing the tag shock mount wont fix your lean.
