Re: 7000 mile trip with 3000 mile towing with Tundra and Outback
The tranny will tell you whether to tow in OD or not. When I towed my pup, OD worked just fine. Wouldn't hunt between 4th and OD and the torque converter stayed locked up. With the travel trailer, it won't even make it into OD unless I'm going slightly downhill.
If you're in D and the tranny is constantly changing gears or the torque converter won't lock up, switch OD off. If the tranny seems happy, stay in OD.
I have found that the large frontal area of the travel trailer is what keeps me out of D. I think a low profile trailer of the same weight (5,000 lbs) would likely be able to tow in D.
