I have close to 14k miles on my '03 (since early October) about 4k of which are towing a light 2500 lbs. pop-up camper. I picked up a larger travel trailer the other night (I'd guess about 4k lbs. ). I definitely knew this one was back there. On the Interstate, I passed a big-rig and when I was past the rig I noticed quite a bit of smoke from the exhaust (it was dark out so I'm unsure of the color). It has never done this before. My guess was that with 14k miles of Interstate travel with little or no load I must have "junk" on the cylinder walls that was burning off under heavy acceleration and a heavier load (than usual, that is). It never did smoke again like that and I tried to make it do it.
Does this sound right?
