I recently bought a trailer from harbor freight for a trip this summer out west before I pack up for the trip I planning I draggin it around home a lot any advice on max weight, tire psi, suspension psi, safe speed, anything I should watch for as far as harbor freight quality "bearings, balanced tires" etc. Also I haven't tore off the stock lights and put my L.E.D.'s on yet, am I ok to run the standard lights as far as the staters go?
