Unfortunately, my only option for winter storage of my larger equipment trailers has been outside in the weather. Two are long GN trailers rated at 24K & 26K and the others are bumper pull trailers at 10K & 12K ratings. It would not be uncommon for the trailer to sit for a couple of months during the winter season. I really do not do much to prepare them for winter storage outside other than slant the front so the snow runs off them. Should I put some jack stands under the axles to get the tires off the ground in order to prevent any flat spots from developing as well as to prevent any possible side wall cracks? If left on the ground would putting the trailer tires under some landscape blocks be better than just leaving them sit on the ground. I do weather coating so that helps to keep the rust under control. How about the brakeaway battery? With the larger trailers they weigh over 7,500 lbs and are tandem dual axles which probably doesn't matter but jacking them up and down as needed in the winter cold with frozen ground sounds like a pain to me. Any thoughts would be appreciated.
