Pod leaning to driver's side

Thats good info. From the looks of the floor plan the 179 might be a little more balanced than the 178 side to side. That might account for a 1/4 inch difference. That you measure a natural list of 1/2 inch on the 179 adds a little more credibility to the technicians claims that it is due to the weight of the slide out. By the way my  measurement was made at several locations with rpod empty on level surface and properly inflated tires and verified with a bubble level and eyeballing.

Again, on a serious note, measuring a 1" list has a lot of variables that make me wonder whether it is accurate.  One must start with an exactly level parking place, have the tire inflation exactly even, have laser level capable of accuracy to within a fraction an inch or millimeter to measure the list.  Simply putting the trailer on what appears to be a flat surface and eyeballing it leads to very substantial inaccuracies.  Our eyes don't see things as we think.  That's why the Mystery Spot near Santa Cruz makes so much money tricking our visual cues into thinking the world is not what it is.

Seriously though, one inch of list is likely, as GlueGuy suggests, to be from weight differential due to the location of heavier stuff on one side as opposed the other. Remember, the axle manufacturers build axles with equal torsion for both wheels, thus if something weighs more, like a slide out, on one side as compared to the other, it will make the trailer list a little.

 If you wan't to have the trailer balanced such that both sides are equal, put some jugs of water in the higher side to the point that the weight balances the trailer.  The advantage, is that you'll have some extra water along, which is always useful.  

It is not likely that one of the torsion springs in your axle is failing, though anything is possible.  These torsion springs, if I understand this type of axle correctly, are rubber rods that twist with the ups and downs experienced by each wheel.  They would likely deteriorate over time pretty much evenly.  Of course, it is always possible that some contaminant got into the rubber during manufacturing that went unnoticed and is causing one rod to be a little more flexible than another.  

Since your Pod will spend most of it's life on uneven roads and slanted parking places in camp sites, a 1" list is not going to result in any harm to the trailer.  

As I flail away on the keyboard drinking my morning coffee and hoping that they don't close for the winter the campground I'm heading to tomorrow, the thought occurs to me that maybe the best thing to do to balance this deviation is to put a small ice chest on the high side and load it with bacon until the weight balances out.  

FYI

I called Forest River. They said up to 1 inch lean is ok.  I still dont like it though - it probably means the torsion spring suspension is going on the fritz. I just wonder if we are the only rpodders that have noticed this problem.
