Kat, Check out the Real World Trailer Weights
located here. These are trailers that have been weighed at trailer meets ready for camping. It appears all 3 are the standard 13' Scamps without the bath - my guess is you can add at least another 150lbs to account for the bathroom.Note the tongue weight
will also go up accordingly as the bathroom is at the front.. as I said its just my guess to give you some idea as to the possible weight
.... have no idea what it may actually weigh.
