I’m rebuilding a car trailer. I went to several local shops to pick up parts only to find they had what they had but not what I needed. So I went online to purchase.
I was still unable to find a single-source to buy what I needed (bearings, wiring, lights, trailer light receptacles, etc) but I located exactly what I wanted - and at prices that beat the crap outta any local offerings. Eight separate purchases in all (plus new decking from the hardware store).
Be careful on your wheel bearings.
Avoid the China stuff if possible, they have a bad quality record.
