The travel trailer we are considering weighs 6,000 lbs empty - probably near 7,000 lbs with clothes, stocked kitchen, water, propane, awning, etc. Our '05 GX handles 6,500 lbs of car/tandem trailer combination without breaking a sweat (without a weight distributing hitch), but we are a little concerned with a high profile trailer that is 500 lbs over recommended gross, even with a weight distributing hitch. Anyone have any experience with high profile over-gross towing?
