The 199dd comes with mandatory package(s), except aluminum vs fiberglass. To me, mandatory packages are not really options, as the TT cannot be built without them.
The only "non-required options" are:
6 cu. ft. Double Door Refrigerator (instead of the 3 cu. ft)
Swing-Away Grab Handle
Blue Tooth Radio w/(2) Interior & (2) Exterior
Speakers, Solar Prep, Backup Camera Prep
6 Gal Gas/Elec 110V DSI Water Heater
Grey Fiberglass Walls
I don't think the 6cu. ft. fridge replacing the 3cu. ft. increases the weight of 300lbs!
The sticker says allowed cargo of is pounds, stating a full fresh wated tank is 300 pounds.
