I would have taken the high road... quietly gone to her and told her.
Sure she will say its ok its just undies and try to make it no big deal.......but it would have been her every thought for the rest of the night... neither will you but you will be laughing
tinted windows- check have me some of those
fog/driving lights-check always drive with them on
trailer lights-yes one doesnt always work , depends on how the wire sits
trailer brakes - truck has 3 that should be enough
over length - nope
speeding - unless you see me at a stop sign...
Should not be any issues i have same truck 07 and haul my 6000lbs boat around no issues. Doesnt like big hills i tend to just run them, and i turn the overdrive off.
