Enclosed trailer question

Like I stated….. It will do it but it will be no easy task. It won't get out of its own way nor be able to stop quickly if need be. Been there done that. I don't care what the others say. I have towed for many, many years. They are not speaking the whole truth about the situation, "What I have is the best syndrome" It is going to be a hurtinnnn for certain! Pulling any type of Grade….

My 26' enclosed weighed 5500lbs dry. Loaded easily 10-11K with fuel, cargo, tools ready to go.
