I used the northern tool 5×8 aluminum trailer. IIRC, the shipping weight (including wheels/tires) was about 150 lb. I estimate my TD weighs about 350 including a battery, so the total wt is about 500lb. the northern tools trailer is very well built. and, being aluminum, it’s easy to cut the members to length with a powered jig saw. it’s about 10 inches too long (again, IIRC from last summer). to get the tongue weight right, I mounted the TD at the front of the trailer frame, and cut the excess off the back end of the frame. it was easy to drill new holes in the members to accomodate the rearmost cross-member at the new location.
