I already own one, but a generator would be really low on my list. It's only really needed in extreme cases, and really only to run the ac. Your necessities will all run off the battery, which is charged off the truck, or lp gas. My generator is an inexpensive ($250) one from Menards. It's fairly loud, but you run an extension cord anyway so just put it a ways away. It's light enough to just put in the bed of the truck. Don't waste time and money on getting fancy if realistcally you will never use it.
