I don't have that model, but I do have a similiar sized Flagstaff. Awning covers are nice and functional. Your gas heat should be good, but grab a couple ceramic heaters which heat nicely, and will save you $ on the gas (if your staying in parks with hookups). The 13.5 AC does OK here in Fl, and we supplement it with a small fan. Electric tongue jack is great, electric stabilizers I don't have, and can't comment on (We have a 16 year old son who does fantastic cranking the jacks...LOL.
Good luck and enjoy the TT.
