We have an Allegro 08, 32ft, class A, Ford, with approx. 7500 miles. We last used it in Oct 09 putting about 2200 miles on it. When we returned we had the oil changed, all fluids checked and put it up until a few days ago when we took it out for an 80 mile trip. In checking the transmission fluid I noticed a little grit on the dip stick. It didn't feel like metal, more like sludge, although there were some pieces that were clearly noticeable. I repeated the process 10 or so times and got hardly any particles on the dip stick. My question is: Since the MH set up for a couple of months could this be just some deposit that settled and was churned up during the 80 mile trip or is this an indicator of a bigger potential problem? Everything ran fine during the short trip.
