Had the camper on the truck when the truck's fuel pump died while about an hour from home. Good Sam saved us again! :)
One issue was how high would it all be if they used a flat bed. In our case they used a regular tow truck and lifted the front of the truck. Watch out if the camper is longer than the truck bed and is lower too. Gets close to the ground back there. They have to pull the drive shaft pins at the back under the truck, so make sure you get those back from the tow truck driver before he disappears after leaving the rig at your garage.
I then found out there is a limit on towing coverage in the GS contract, so I had to pay the amount above that limit. It was all about me wanting it towed home instead of to the nearest garage. That is because the garage we use is near our house and can walk there, so got the rig towed to that garage and left it there to be fixed and walked home.
Anyway, yes--it is worth having the coverage for the TC. ( in our case it also covers the Class C and our cars too- but you need the Platinum for a MH which is a bit extra. No big deal.)
I have been saved by Good Sam more than once. Only problem was with my cell phone coverage, where they put you on hold. You need a plan where you can stay on the line, long distance to the States (not a problem if you are already there). So the big lesson is to not just have Good Sam, but also an adequate cell phone plan.
