It's been a while since my last post but I have a question. We have a 2010 Toyota Tundra SR5 towing a 31 foot 2010 Keystone Cougar. I weighed the vehicles at the scales empty they weighed 13240 lbs. The overall weight for the truck is 16000 lbs. In you're opinion, how close should we get to the 16000 lbs to allow for safe stopping distance. Thanks
