There should be a date stamp on the tires. The code is four digits. First two are the week of the year and second two is the year. So 2620 would be the 26th week of 2020.
Most will tell you 5 years from manufacture is about as long as you want to go on tires but there are some opinions that the crucial time period is when they are mounted and filled with air. Some say if they are stored indoors and not inflated that they donít really age much, but there is no debate that once installed and inflated they begin to age. This is word on a tire or tire that gets sun exposure, which is commonplace on a trailer as they tend to spend long amounts of time outdoors in the weather and can sit weeks or months without moving.
Also, on the subject of tires, there are some really low quality tires out there and blowouts can cause significant damage as they can tear apart the underside of the trailer and also damage the rim. It can be made worse because unlike a car you might not notice a blowout on a two axle trailer.
So please pay lots of attention to them, check their pressures when cold (you will likely need a pressure gauge that reads higher than the one in your car) and when you replace make sure you get tires that have the load carrying capacity needed.
I would also buy a new fresh water hose, water filter and pressure regulator for when using city water while camping.
And check your batteries too. Check water levels and resting voltage. Wait at least a couple hours after plugged in and see what they read. They should be 12.6-12.7 volts resting. Donít be fooled by the reading the minute you stop charging. Batteries will almost always show full when you stop charging but they can drop quickly and there are few things worse than trailer batteries that go dead in the middle of the night. Heater wonít work (fan uses battery), fridge will stop cooling (propane is method of cooling but batteries are needed to work the system). And hard wired smoke and CO2 alarms can start
beeping as well.
And keep tools with you. You might need a screwdriver with a square tip for some screws in the trailer, crescent wrench, small pipe wrench, hammer, duct tape, plumbers tape, etc., fuses, extension cord, and make sure you can jack up and change a tire. Practice that before you hit the road!
Enjoy The trailer.
