(except for holidays and major events such as Burning Man at $2700/wk.  Compare to commericial renters at $4000 + $99 'prep' fee + $200 'cleaning' fee +  $3/hr generator fee + $0.29/mile + $5/gallon gas if the tank is not totally filled prior to returning, etc. etc. = $5000+!!!)

Unlimited miles.

Unlimited generator usage.

No need to bring it back filled up with water or gasoline or propane (but i'm lazy so the gas and propane tank may not be filled when you get it).  No need to bring it back ridiculously clean (as long as it's not filthy, stained, or stinky, and of course you'll pay for anything damaged).  ** I do want you to dump the black & grey water (gross!), though someday I'm hoping to put a dump station on my driveway so you won't have to do even that.
