Hello! I too just bought a 2019 sunset trail 253RB...My first mod was to put heat in the bathroom! I do not know why they did not. Easy job though. Just ran an additional duct. Also installed a higher velocity fan in the bathroom, installed and wired a fan in the roof vent in the bedroom ( what a difference!) Replaced furnace control board in the furnace, new control board for the gas to electric fridge. All boards are Dometic and go out soon as I found out. Better boards are made by Dinosaur Electronics with a three year warranty! Up graded propane tanks to 30lb with gages, Water heater was too hot so installed an adjustable temp one. Overall It is a nice trailer!
