got my first trailer last year to haul around my UTV and the dealer said to bring it in for service every 6 months. But everyone i have talked to says they have never done anything to their trailers...ever, dosnt mean their right just want to know if this is a service i can do or its best to bring it in or maybe there really isnt anything you need to do to it.

You can do it yourself easily. Main things are going to be keeping stuff like ramps, jacks, or similar greased. Overall keep it pretty clean and wiring neat and tucked up. Tires are treated like any other tires. Trickiest part and probably the main thing is wheel bearings. They need grease to last but it's not something that needs to be done all the time

X2.

But we all know if we pull trailers often, there is going to be a problem, especially a dog trailer. Also, keep up with your tire dates. I have made it a habit not to use a tire over 5 years old if I am going to be hauling heavier loads. Always use an 8 ply minimum for a trailer tire.

All my trailers get their bearings repacked every spring. That first time you're rebuilding a trailer hub on the side of a highway will teach you quick. Jacks and bulldog hitches get greased as needed, generally a couple times a year. Other than that, there's not really any other routine maintenance to do.

Servicing bearings is a good idea, but I feel like every year is just as crazy excessive as taking it to the dealer every six months... unless its a commercial use or incredibly high mileage/year trailer.

I recommend checking the inflation of tires and lights every time you use it. Floor boards are pretty self explanatory. For a flat bed that doesn't get dunked in water like a boat trail I would think every couple to 5 years or so on trailer bearings would be more than enough.

My trailers are used daily, and stacked heavy. Except for my little Big Tex, but if you've got all the parts out to do four axles, might as well do the fifth. An hour's labor and a handful of grease is cheap insurance.

I use a thermal heat gun to check my hubs during stops on road trips. They should be below 130° at all times. Loaded, mine runs < 120°.

What the guy's said, but surprised no one mention brake adjustment, you should check that every 6month if you use it much, or when you feel them getting week. It will require you to jack up each side/wheel, turn the little barrel nut until they just barely grab (each brake). Barrel nut is inside the drum, you get to it through a small opening in the bottom rear of the drum, should be a little rubber insert to keep the dust out.
