Aluminum durability

[rodneym]

Hello,

I'm a current SPF owner seriously considering a Kirkham.
I've read nothing but amazing things about the quality of Kirkhams but my real concern is the general durability of aluminum.
In SoCal, there's quite a bit of highway debris that gets kicked up, like tire chunks, small pieces of smashed pallets, etc. I'm pretty good at avoiding such things but.......
On a glass car, the road debris makes for tiny chips in the paint but what kind of damage happens to a Kirkham? Do you guys get dinged up in the front?
Is it true that you can dent a fender by working on the car or are these stories blown out of proportion?

Thanks for any input.

Rodney
