Thanks for your reply. I didn’t consider tow weight that much; I was more worried about the age/mileage of the MDX. We are also using movers for the big things. I just wanted some extra space to take our essential items with us in the trailer. The 5’x8’ trailer is 900 lbs and with an 1,800 lbs load (the trailer’s rated max) would certainly be under the 4,500 lbs limit. Does this sound like a better idea? Do I need the trans cooler or not?
