Hi, I’m Dekker , the bloke behind Volv-Oh.

I’ve lived in Volvo cabs for years. As every Tramper knows, some things Volvo absolutely nailed… and a few things they definitely didn’t.
So instead of putting up with the annoying bits, I started fixing them — one small upgrade at a time.
Every product I make begins with something I needed myself . I spot a problem, design a better way, print it, test it, tweak it, break it, improve it… and only when it genuinely works does it earn the Volv-Oh badge.
There’s no company here. No team. No factory.
Just me — a Tramper making tough, non-destructive, cab-friendly fixes for fellow drivers who want stuff that works properly.
If something I make ends up in your truck, it’s because it’s already earned its place in mine.
Volv-Oh, That works!
