Quoted from krazy53:I think you might be able to fit two pins in a Tahoe, at least an 03 model. I did it in a Suburban and I believe they are the same width.
I have an 03 Tahoe and don't see how you would fit two in. The width should be the same as a suburban.
Here's a pic of my WH2O in the back. Doesn't really seem like enough room for two.
