I just read through this and I noticed something, you are planning on using this TT in the winter in ND and MN. I don't think you are going to find any trailer in the weights you are looking at that is going to be 4 season capable. Most trailer that handle cold weather are heavier. The tanks are all enclosed and they have more insulation than you well find in the light weights. Also towing when the roads are ice/snow covered is not something that is fun either.
If you think that you are only going to put in 150# of your stuff (as stated in earlier post). Then you state that you are talking everything you own in it. Si all of the stuff you own only weighs 150#? This is all of your pots and pans that you say you need because you like to cook.
Something else I didn't see posted anywhere is you keep talking dry weight of the trailer. Dry weight is just that, dry no water, no batteries, no propane or tank, no water, no other items that are needed to RV or any other things that are added to the RV as an option like an AC. For instance water hose to put fresh water in the RV then sewer hose to dump with, chemicals needed for the potty and toilet paper. I come from the truck camper forum (but have had many trailers also) and we figure you are going to add about 1,000# of
additional weight to the dry weight.
I wish you good luck on whatever you decide to do but remember to be safe not only with your rig but yourself also.
