Need assistance with a font, image attached

Ive been told by the owner of this logo that the font used was totally custom built, but I find that hard to believe.

Any help would be greatly appreciated.

These are the only letters I have to work with, hopefully it is enough.

Thanks in advance for any help!


it looks like it's based on House-A-Rama Kingpin by House Industries
(a bit slanted and modified)

I found it using Find my Font -
