You might want to establish a preventive maintenance routine and schedule to include battery water level check, drain the water heater per the manual, blow out the burner tubes of the wh, furnace, refrigerator, and make sure all external areas of these are clean and free of bugs and debris. Make sure all hinges for the steps, moving parts of the stabilizers, have a squirt of silicone lube, or wiped down with WD40. Since your unit is brand new, you may want to look at a spray on / wipe off product that has UV protection. Two the come to mind are 303 Protectant, and Lucas Slick Mist. Both are very easy to use, and as a result don’t take long or much energy to do but will help keep the TT looking new for a long time.
