Good comments above. Only other observation is if you have a steep driveway upsweep off a downsloping street, you need to be careful in three places: Under rear of trailer, under tongue jack, and if the back of your tow vehicle is vertical (like an Expedition or Suburban, or truck with rack or shell) that the 'v' created by the back of the TV and front of the trailer doesn't touch. If it does, you can bridge with boards.
