Newbie - 1st time towing Car on Tow Dolly - Tips?

I check the straps and tighten them everytime I stop..the one thing I do is after about 25-50 miles I find a pull over and tighten the straps...while I am out I also check the tires and do a walk around of the rig...I tow with a dolly for about 5 years and never had a problem...oh yea..remember the wheel bearings on the tow dolly..mine had external zerts on the hubs, so greasing was easy..take care and good travels
