Question: I purchased a travel trailer late last summer. How often should I grease the bearings? I have gone less than a 1000 miles with the unit.
Answer: There is a lot of information on websites that say anything from twice a year to once every 5 years. We would recommend that you err on the side of caution and have them greased at least once a year or 10,000 miles which ever comes first.
No matter what you read or we read, it really comes down to your money and aggravation if something goes wrong because you guessed incorrectly. Your best source of information is your owners manual for the recommended wheel bearing service interval. I would imagine that there are differences depending on the bearings that the manufacturer used on the travel trailer. Ultimately the manufacturer is the authority in this regard.
