All the trouble (and cost) in getting extra battery capacity! Has anybody considered Lithium ion batteries, half the size, quarter the weight, twice to three times the cost. Except that the lifetime cost is probably close to the flooded lead acid ones, it's likely that the batteries would outlive the coach. Over the next few years we are going to see these batteries drop dramatically in price and they will be the battery of choice.

Depends on what you do with your coach. I get by just fine with the AutoZone special in the house battery position, because all it has to do is run the icebox and lights at fuel stops and while the coach is parked waiting for me to hook up shore power. And, it has a solar charger which keeps it hot properly.
For those who dry camp, it's a very different concern. I go once or twice a year to a dry camp situation, and run the genset for that one, using my homebrew generator stack. After a very bad situation, that site notes "During inclement weather Sunday afternoon, the Club will provide towing service for RVs." When it rains, the place becomes a bog.

Me?
After doing all the boat electrics for years, I'm now waiting for the battery packs from accident damaged hybrids to show up on the market - cheap. 2400+ watt hours of flooded cell is about what we can afford these days, but it wouldn't take much for one of those stacks to show up at the right price/value to make me think long and hard about the investment.
Yes, yoy have to restrict the use to the middle, but you can only use the top half of a flooded cell before you do it harm.
