I was able to find the info on the NorthernTool site though in the Q&A section of the trailer page. According to their website, the height of the metal frame/deck to the ground /bottom of the tire is 20.2 inches. Subtracting 3-3/16" for the frame rails that puts it right at about 17" to the bottom of the frame rail.
Also according to their website, the distance from the back of the frame to the center of the axle is 42.9".
Thanks oldsmokey, I'm glad to see some chatter and some NT trailers still on the forum. Like I said in my response to bobhenry, I've about given up on the NT frame since they no longer sell the frame parts separately. My plan is now shifting to buying the C-channels from a fabricator and building it myself from scratch.
