what does tae the bulge out mean? is that jacking the trailer up so there is no pressure on the tires? if so then i dont see why you would have to. my trailer sits on its tires all year round until i take it out. are you leaving the camper at the site year round?
You should not jack the trailer with your stabalizer jacks to remove the weight off of the axels this will cause the trailer to bounce and may bend the frame.
