Where are you located so we can reccomend a place to have your trailer looked at?

2 main reasons for trailer break downs are tire blow outs and bearings heating up from lack of or compromised grease.

I would make sure and check the tires for dry rot and proper inflation. Inflation should be checked when tires are cold. I would also make sure I had a good spare and a jack to change it out if needed.

As far as the bearings, for a trip this long I would definately take them out, clean and repack. I might even have a spare set handy just in case.
