Enzo, this is my regular mechanic, who also happens to be a trailer guy. If you tow only 3000 miles a year, you may not need an annual bearing inspection and repack and lube and ritual sprinkling of holy water, which is what I always get.
But we tow ten thousand miles a year, in very rough conditions, and we have only a single axle. The one axle means that there is that much more impact on each set of bearings.
I understand why you tow only 3000 miles a year -- you live in Colorado, so there is no need for you to drive a thousand miles (like I do) just to get to Colorado! ;)
