Between you and SHelby in AK my christmas list is getting unmanageable. I walked into a hobby store to get my son an RC airplane the other day, I walked out with like 12 GT slot cars for the track that found it's way in my basket.....
One of the best options to put on any trailer is an electric tongue jack. They are powerful enough to raise the front of the trailer while loaded and connected to the tow rig. Even a slight downhill can now become an slight uphill at a touch of a button. E-track with an over the top strap is also the way to go.....once you've used a trailer like this you're spoiled for life.
