Ed, first off, I clicked on my tab key to indent, which deleted all that I had written....don't know if you received my incomplete msg or not.
I, too, am a rather newby 8310 owner. We camped in it for three weeks and then took a 4000 mile trip thru the Wyoming high country. Going to camp at Ft Pickins State Park next month. Each and every time we use it, we learn something new....often from our previous mistakes. The only outstanding question I have at the moment is whether or not I should remove the water filter prior to winterizing...(I did).
Here are some issues that we have encountered....would be interested in hearing of your own experiences:
Busted off cabinet doors while both opening and closing the slides before we finally always use bungees.
One tire wore away....they were supposed to have been "D" tires but found out when being replaced that they were actually lightweight "C" tires. Others with more experience have recommended automatic replacement with "E" tires, which I did. BUT, while being replaced, the tire shop found that my axle was coming loose from the trailer, which had caused the tire to wear away. Need to periodically check the axle attachment as well as lug nuts, tire pressure and wear.
I have not found a good solution to the stupid two-separate waste tanks configuration that must dump into a single sewer pipe. Nor an easy way to access the galley tank drain, far beneath the slide. Any ideas?
Twice, my propane has shut off when the tank still had ten or so pounds in it. Don't know why. Now I use one tank at a time rather than open them both, so that I will know when I am half-empty. It is easy to simply switch tanks rather than to suddenly be totally empty. I also cut a hole in my plastic tank cover so as to readily see the green/red gages.
Some RV park sewers will only fit my flex pipe while others require a doughnut on it to make a firm seal. I carry a doughnut separately. Also, the plastic ends of the rear bumper that contains a flex pipe tend to come loose...I drilled small matching holes, top and bottom in which to insert long nails thru both the bumper and plastic ends to always keep them in place.
I have installed quick disconnects on both my city water and black flush tank fittings and on the ends of my hoses....this is SO MUCH easier than screwing the threads. I don't use a pressure reducer on the black tank flush. I'm converting from a pre-set 40psi reducer to one with a guage so as to have better pressure at 50psi which is supposed to be safe.
I thought that I was keeping enough water and frequent flushes into the black tank and flushing it well, but one time the toilet backed up because there was a pile in the tank directly beneath the vertical toilet pipe. I solved this by moving around a long sturdy stick down through the toilet, to break up the pile and then pointing an unregulated water hose stream directly down into the toilet to blast away the remnants.
Enough for now....hope to hear of your own experiences. If easier, you may contact me directly at firstname.lastname@example.org
