The tires seem to be the biggest concern. They are 225/75r15 and their combined weight rating barely equals the GVW minus the hitch weight of the trailer. I saw a brochure that listed the same tires used on the larger units which means they are deffinatly overweight for the tires.
The ones on this rig appear to be the originals based on the date. Going to have to replace them soon! Would like to get 16" wheels but combines with tires that gets spendy after having just put down a down payment.....
