Overloaded tow rig?

Ha, yup, us Podophiles are not the only ones who need to worry about stressing our tow rigs. Followed a new Ford eco towing a Cougar High Country 5th today. The route is a 2 lane area of rollers and foothills. It was very pod friendly, even with our 6 cyl Taco Tacoma, and I never held up traffic towing there. Nice and powerful as the eco's are, this guy couldn't say that. Anything can be stressed with poor combo/loading choices. Someone on this site, I think, said they'd seen more big rigs than Pods overloaded and struggling. Poor guy looked pretty stressed himself, as his traffic jam rolled by him at the first available passing lane. Been there in the past. No fun.
