Don't be too concerned with getting the "smallest possible" toad.
Once you get more comfortable with driving your unit, you'll realize that towing isn't as ominous as you thought it would be.
Amazingly enough, the toad goes exactly where YOU do! :) We tow an HHR, about 3,000lbs, and we don't even know it's there, other than leaving the backup/rearview camera on so I can monitor what's going on back there. The backup camera also helps with things like lane changes when towing...takes the guess work out of it as you can clearly see when you've got enough room to move into another lane.
Remember, there are 100s of thousands of people towing cars behind RVs every day. They do not have super powers...they are not much different than you are :)
It's sort of like the perception of flying. If you've never done it, you think it must be incredibly difficult. Talk to pilots and they'll tell you that if you can drive a standard shift car, you can pretty much fly an airplane ;)
Happy Trails,
Jim
