Thanks guys for your advice.
Regarding the tires, they had quite a belly in them but did check out at 44 psi. We are running car tires on the trailer, 205 / 75 / 15 from memory. I know we "should" be running trailer tires, but it ended up being a $$$$ thing. Maybe the tires should be cranked up to 55 psi as well as closing off the front grill
THanks for all the responses.

he had to haul a pretty heavy load so he added more air thinking the tires would handle it

Wind drag is doubled from 55-70mph. The rate wind drag increases is exponential,not linear. Wind drag increases in a HURRY.
Another figure I've come across is that you lose 2% of your fuel economy for every MPH above 55 that you drive.
Drop 'er down a few mph next time and see what happens.
