These trucks are not bought by "recreational" users ... it's a very serious truck. You can even see the frame peeking under the body. (running boards are hiding it here). I've seen some people with RVs with these things but you have to do some serious hauling to even have one of those monsters in the driveway.
The six-speed Allison 1000 transmission/Duramax 6600 diesel combo is what you want if you need to haul your house or your pet elephant.
