We got our 2011 Pinnacle in July of last year and it is a 36RETS. We originally towed it with an F250 diesel power stroke. You could see the tires squat after hooking up. We were trying to decide whether or not to install the suspension air bags or trade up. It was a no brainer after we encountered strong winds returning from a trip to Branson last fall. The wind pushed us all over the road. Safety is definitely a big issue and if you are in an accident and they can prove you are overloaded, you may have big problems with your insurance. We now tow with an F350 power stroke diesel DRW and feel much safer.
