Towing bambi with honda odyssey 2011

Honda will tow 3500 lbs, the weight of the Bambi. Will have hitch installed and transmission cooler. Have a years experience in traveling light. Did a year in a Tnterstate



Honda dealer says its a go but the down the mountain ride is worse than up keeping brakes cool. Use lower gear which I am used to living near Denver.



Replace transmission and brake fluid more often.



Plan on touring for months at a time, not just weekends.



Any thoughts on if this is going to give me troubles?



Thanks Ty
