Since I deliver TT's and 5ers to dealers I have to go off duty for 10 hours after driving for eleven, too. However, I make it a policy to avoid truck stops. I've seen campers that were side swiped or bumped by tractor trailer rigs in those settings. Many drivers don't even know they hit anything and many wouldn't stop even if they did know it - leaving the RV transporter holding the bag for damage repairs.
When I have to stop I go to WalMart first. Like others have said, it's a good opportunity to get some dinner and such.
