Light Towing vs. Transmission Life

[rtribble]

My old Jeep Grand Cherokees', with 145,000 miles on it, transmission just went out. I'm the second owner and never used it to tow and have changed the transmission filter twice at 50,000 miles each. The previous owner used it to tow his ski boat and put 12,000 on it before I bought it from him. Given that I pamper my vehicles, I felt the transmission failure was due to it's previous towing service.
I have just purchased a new Sequoia Platinum which of course comes with the towing package.
The problem is that our Sun-in-law owns a 20' Cobalt and has relocated about 150 miles from the lake he uses his boat and we keep our boat, a 36' Carver, on. He has suggested that we could use our Sequoia to tow his boat to and from his new home when we all go to to this lake which would be about 300 miles towing round trip. His boat and trailer would probably wiegh in at around 5,000 lbs.
I am concerned that this towing could substantually shorten the life of the Sequoias' transmission over time and would perfer he keep his boat stored near the lake where our towing would just be a short distance to and from the lake instead.
Do you think my concerns are justified about the potentail premature transmission failure (and of course the higher rpms required to tow on the freeway at 75 mph and assosiated engine wear) or am I being overly protective of our new Plat?

The transmission was designed for life in the Tundra 5.7, Landcruiser 4.5 diesel and 5.7 and Sequioa 5.7. The transmission was tested and tested to haul up to 10,000lbs all day long. Should not be a concern for 5000lbs.

Maybe a little overly protective IMO.

I'm planning on regularly towing a 7500lb boat and don't expect any issues (although I am getting the extended warranty which should cover me for my time owning the Sequoia). I don't think premature tranny failure is an issue however you will use your brake pads up sooner as well as the need for rotors sooner than if you weren't towing. You'll also want to change the oil more frequently with the long distance towing you plan. None of these are a big deal but they are costs to consider in addition to the significantly lower fuel economy you'll experience while towing.

Thanks all for your imput, I originally was thinking we could pull a small camp trailer with it occasionaly but after reading and thinking about it I got the impression that we would need a bigger/heavier vehicle for towing especialy after the Jeeps tranny went belly up.
While I will still try to convince our son-in-law to keep his boat at our lake, I guess it won't kill me to tow it that further distance if I have to.
