The dealership said to ignore these bearings for ten years unless we really do a lot of long rang traveling.
Hahahaha! Check the Owner's Manual or call the manufacturer for more reliable information when it comes to inspecting and servicing bearings. Typically I inspect every year which is what my manufacturer calls for. This gives you a chance to not only inspect the state of the bearings, but also the grease, seals, and any signs of leaking. It doesn't take all that long to pull the hubs and inspect. You will certainly spend a lot more time on the side of the road and repairing damage when things go catastrophically wrong. The saying goes, an ounce of prevention is worth a pound of cure.
Even though it's a 2017, it won't hurt to check. RV manufacturers aren't the gold standard when it comes to quality control. Often times things get missed or done improperly. Not an RV manufacturer, but I once receive a new cargo trailer with empty hubs. The bearings had about a tablespoons worth the grease on them that looked a lot like Vaseline. Also the bearings that the trailers come with are the cheapest of the cheap. It's not all that common, but sometimes trailers come equipped with defective bearings.
