I researched that very question a few years back. At that time I found Newmar to have the best Class A insulation package. I now have a Winnebago and it's like trying to heat a cardboard box when it gets down in the low 20's. On the flip side it's hard to cool in hot weather.
Don't be to surprised if Ford turns it down as warranty. If your insurance has to replace it this time and it shatters again Ford will take a second look at the problem. But make sure you show it to your dealer so even if they will not cover it, it will be on record.
It will jack knife the tow if you backup far enough. But if you watch and back careful you can back up on hard surfaces to some degree. I would not try it in sand or soft ground as it would put a lot of force on the tow bar.
I use a usb wifi adapter with a Yagi antenna and I'm surprised how well it picks up signals from the side. I usually put it on the steering wheel and try different directions and you want it vertically polarized. Where I spend the winter it takes four half bars signals and turns it into 15 three plus bars.
Do whatever it takes to add the Yagi antenna as most come with a SMA female pin or N female.
This will not help the OP with a Verizon cell signal.
We have been going south for several years. I think there are two major runs for the south. The first being right after Thanksgiving and the second right after Christmas. If your thinking south for the fall of 2013 you better get to making reservations now as many places are already booked.
I always fill my tank and use from the tank to keep it fresh. My fresh water tank is 90 gallons and we find this will last about 5 to 6, days. No need to skimp on water usage, just refill the tank when it gets low.
Just pulled into a new campground today and to level the front tires are off the ground about 2". Rear tires are the important ones not to lift off the ground. As far as un-level the the fridge is the most important thing on board that needs to be near level.
A friend of mine upgraded to a newer used diesel pusher from a trouble free gasser. He sweet talked the wife as she was dead against the upgrade. They bought the diesel, 2500 miles down the road it was laid up with nearly $9000 of engine repair. Like he said had he been near home he would have had it towed home and he could have repaired it for much less. But 1200 miles from home is a different story. That was 3 years ago and the wife hasn't forgot it.
