Consider going to Harbor Freight and building an "oh crap" trailer toolbox. I bought a bottle jack, some inexpensive tools, gloves, ratchet tie downs, headlamp and anything else I could think of. Then I went and got a spare set of bearings, seals, oil/grease, some anti-seize, brake fluid and a few 4x4 blocks. This toolkit is about the only thing I never tow without. I've yet to use it, but I guarantee that the first time I leave it at home, I will need it. It's just science!
