I know this is is a while after the fact but I have the 46540 and it is indeed loud; its not annoying when you're inside but its certainly noticeable. I primarily use it for tailgating and we position it at the opposite corner of the camper from where we'll be and it certainly doesn't make us any friends. I'd go so far as to say there is no way you would want it running while you or those around you were trying to sleep. As for storage and transportation I have a platform on top of the rear bumper to transport it and then set it on the ground when its running. Also note that it is indeed rather heavy and moving it works best with a buddy. On the bright side, it certainly powers everything in the camper and is actually pretty good on fuel. It has ~4 gallon tank and when I run everything except the A/C (fridge, microwave, lights, stereo system, and tv/satellite) it will run about 12 hours on a tank.
