I run according to traffic and road conditions. Rarely are we in a hurry to get anywhere. I do not like to be slug blocking lane except when traffic/conditions require. This would be same pulling double axle car trailer with bracket Camaro. The trailer alters nothing but clearance and bigger gap for stopping.
Have had a few urgent stops with and without trailer. Braking is impressive on e450 chassis and anything remotely loose in RV goes flying.
