We can get 100k+ miles out of many automotive bearings, but can't get trailer bearings to last 10k miles without servicing or replacement?
I've always thought the same thing, only thing that comes to mind is the wheel/tire size. Since they are so small usually 14-15" range. They are spinning significantly faster and with that is more heat which causes the bearings/grease to wear quickly. So, 3-4k tow miles is like double or triple, but still it's not like a lot of miles
Also keep speeds under 60mph while towing, especially an enclosed. Helps extend bearing as well as tire life

From a tire perspective (my information came from Phil or PTS), trailer tires a do not have the same speed rating as passenger tires (there are a few that do).
As far as hubs go, my guess is cheap parts with more load being placed on them and not having that load spread out (axles not as far apart as compared to other vehicles)
