Can one of you guys tell me the actual Length of the XP4T? I know specs say 146", but is that right on, and is that from the end of tire to tire? Next question, how far out do the tires go beyond the body. My toy hauler is only 142" so I’m wondering, if I were to get one, if I could get smaller tires to help shave 5" or so down in length to get it to fit.
