harlee, the generator issue is being talked about by quite a few, just not here on this forum.
The parts for the generator fix are a little of a moving target right now. Initially they said heat shield, fuel line wrap, and new bay door with louver. Thor called me yesterday to tell me they are not doing the bay door, just the heat shield and fuel line wrap. The part number for these two are:
Heat Shield- 0252153
Fuel Line Wrap- 0245385
If you decide to take your rig to a dealer to get these repairs done, these are the parts they need to order/reference.
BCintor, funny you should mention the water heater. Ours has been not quite working right. I had already adjusted the flame/air deal in an effort to make ours work better, however, ours really does not work. The flame is nice and blue and burning correctly, however it just is not making hot water. Fooled around with it for about 30 minutes, finally just gave up. Read the instruction manuel twice, but that thing is worthless. Wife is just washing dishes with cold water. We have showers in all the RV parks we have been staying in so not a huge deal.
Lesh, my wife drives off and on just to give me a break, and so far, she has done pretty well, and we are MH+20 ft trailer hauling our Jeep. I think you will find its easier than you might think.
Since some of you apparently don't use other forums, you all might want to Google "cheap handling fix for F53 chassis". This handling fix takes about 30 minutes to do and apparently does wonders for your handling and body roll. I did it on mine, but did it from day one, so I can't say how it drove prior to the fix to compare it. The topic is 50+ pages long so its a good bit of reading, but so far I have no complaints.
Another good thing to buy and keep on your rig is one of these:

I don't have this one, picked up one similar at the hardware store here in West Yellowstone, but was going to buy this one. Our rigs acquire so much road grime from traveling, and it got to a point, where every time I went to open a bay door to get something, my clothes were covered with dirt. Took me about 5 minutes to give rig a quick scrub to take off the grime. A lot of parks don't want you washing your rig, but when I tell them I just need to get some dirt off real quick, they have all said no problem.
