Well homies I was down at my Jayco dealer on Friday picking up my Expanda after getting a little work done. I walked around sticking my head under some campers and Expandas checking out there axles.
There were axles under slung and over slung everywhere depending on configuration. So I asked the question what to
GO.
I was told this; 2t axles on camper trailers are under slung. I then asked why has the 2011 mdl Expandas have over slung axles (mine doesnt 2010) he said that they are forever changing things slightly during the production year.
The standard axles on the camper trailer (Outback) are generally over slung. They wont over slung axles on onroad models any more.
Flamingo and Swan nearly all are underslung because they have 2T axles.
I think this is what they said
I dont think they knew the exact reason but I gave them someting to think about.
