For leveling , you can use the wedge like anderson levelers or get a ball leveler if its single axel. And at 3500 lbs it should be a single axel. Single axels are a bit harder to back up because the respond quicker. But you got that. The bal leveler can be raised with a electric drill or by hand. I use the curved leverlers you drive onto now because i have a tandom axel trailor. Wdh , not needed. I would get a small sway control, cheap insurance. People say well my new TV has sway controll, yes it will. But thats for controlling after it starts swaying. A mounted one stops it before it happens. For the weight of your TT the add on friction arm one should do and its cheap. Have fun!
