Having only had our rig for 2.5 years I, too, have been under the wrong impression.
Knowing that one should accelerate slightly to maintain control until a safe pull-off is a new one for me.
Both videos underscore the need for us all to get our rigs weighed...and possibly put on diets. Don't use your rig to store "stuff" from your house. (How many of us put something in our rig only to never use or even unwrap it?) Even I am guilty--I/we still have yet to measure, cut and place the non-skid mats for our cupboards--even after 2 years--and one of our games, Scattergories (I think) is still shrink-wrapped! I guess the destination and company is more important than the drive and spare time.
Our rig is in for a re-built engine being replaced under warranty--I'm gonna see if our tech will have it 4-corner weighed on the way back to his Orange County facility--I may have to shift storage items.
