its a V6 4x4. I am moving cross country, east coast to mid west. I want to tow a 5x7 utility trailer with some bins. No appliances or anything extremely heavy. I know the manual says it can tow this, but I want to know from experienced mechanical people.. is this safe for my vehicle? I am worried about the hills and my transmission. Are these little suvs capable of towing weight for 2200 miles? Will the high mileage matter? (145,000 miles)? thanks..
