It's been perfect for us but we have grown out of it. 815 is made for both long and short bed trucks 6 & 8ft. We pull our 3 horse slant load horse trailer behind it. Fully loaded and super clean. The bathroom door is removed for more elbow room but we have it and can put it back on. Has holding tank about 18 gal, a/c, heater, tv, dvd player, surround sound, refrig, microwave, shower, toilet, outside shower and faucet, clothes rack, lots of storage, boot box, sleeps 4 comfortably. Just installed LED lights, 3 way fridge, propane oven is amazing, 3 burner stove and everything works! PM me.
