it has been 2 yrs since i did it last and still do not plan on doing it any time soon!! Just keep an eye on your tires and hubs. I was also told it can go for years between changes.
This is probably true but I'm at the opposite end of the spectrum. At least once a year I change the wheel bearing oil (I have the cool hubs too).
While it's drained I jack the wheel/tire up and check the spindle/bearings for correct tension. I seems they almost always need to be tightened just a touch.
The problem as I see it (with a big heavy boat especially) is that if there becomes too much slop there will be more pressure on the inside edge of the tire, and of course the bearings themselves, if left unchecked both will wear out prematurely.
I'll admit that it's not the most fun/pleasant task but you're only talking about a half an hour a wheel and a few ounces of gear lube too. My trailer is an 08 with the black rubber caps that get filled halfway. I always fill them halfway and wait about 15 min. for the oil to settle to the rear seal. Then I put the black rubber cap 1/2 on (presure on the botom to keep the oil from running out) and shoot a little extra oil in before snapping it all the way in place.
