I tow my 22' cruiser with an '06 Sienna with about 115K miles on it. I tow about 3K miles per year. These Sienna's have a tow package with appropriate extra cooling and the like already installed and I have had no problems (including traversing the mountains of western MD and PA in July).
In normal driving, I keep it in 4th gear. On long straight flats it can go in D. When going uphill the speed will bleed off. Don't try to maintain your cruising speed uphill and it'll be fine. It would be nice if there was a way to hold the transmission in 5 (instead of 4).
I put airbags in the rear springs. These help a lot with the ride comfort and firming up the back end.
Make sure you have a spare for the trailer, tools, and a jack that can lift the trailer (the Sienna jack won't handle it). I got a small bottle jack from W-M.
When towing at the Sienna tow limit you have nearly doubled the weight of the vehicle. It will accelerate, stop, and generally perform accordingly.
You can get a ScanGauge and plug it into the diagnostic plug if you are concerned about the tran temp, but I don't worry about mine.
When you stop you can check the trailer hub temps with your hand. If you can't touch it, something is wrong. Also, all the hubs should feel about the same.
Get a cushioned tow ball mount. It will eliminate a lot of the "clunking" in the hitch that will really get to you after awhile.
