Hello,
To add to the CONSTRUCTIVE part of this post......
I don't have much info on towing a large trailer near the max. Here's what CR said:
"With the V6, the RAV4 towed our 3,500-pound trailer to 60 mph in 16 seconds."
I did have some input, take it or leave it, regarding the tow package.
I bought an aftermarket hitch and wiring harness for about $150 total (I think!). The hitch was 4 bolts and 30 mins to install and the wiring harness was actually more of a pain. I had to remove a few plastic trim pieces and such from the back to get to the wiring, so you'll want to do it on a warm day.
Here's a link to a factory wiring install:

It's also here, but the site is down 'til next week:

Also, I did NOT run the wire all the way to the battery, but found a 12V in the back of the RAV that works fine.
Good Luck!
