my thinking is if you can afford them get them.
I was driving home from IRG 2014 at 55 mph Cal. speed limit for trailers.
A large Van came up to our left then disappeared. I bent forward looking for it only to see it running into the side of our car scrapping along side then taking out our rear-view side mirror
and forcing us into the guardrail.
I had slammed on the brakes and slide for some time thought this not so fun event..... and then it drove offfffffffff.
several people had been following it before and after the hit.... they went off an exit and then came back on and tried to run one of the followers off the road.... Then exited in Paso Robles, ca and hit a stop sign.
I often think if I had had brakes we might have missed her. may have stopped sooner.
maybe this drunken driver saw the cute teardrop and came over to take a look.... I have a salvage title on my car now and the shock was broken and some damage to the trailer from the guardrail. we made it home alive but a little shaken.
