I thought about swapping mirrors, but the power folding feature is more useful on a day to day basis (parking it in the garage) than permanent towing mirrors. The little temporary tow mirrors are adequate for the times I'm towing.
And yes... it is fun!
The toyhauler helps add to the fun too. It's nice to be able to stay right in the pits. Great atmosphere. It's particularly nice at those tracks that are in the middle of nowhere, not to mention there is much less of a theft risk than staying at hotels near the track.
