Yeah, you will likely NOT get the
Regent,
Marathon and the
TB across, UNLESS you have the
Marathon RFing, in the middle,
Regent outboard and the
TB outboard, BUT when you get the MA
FFing, due to the
REgent's Side, you won't be able to fit it. I have 2
Regents in a 2003 Tahoe, so I can sort of relate!!!! LOL!
In your situation, the
Nautilus would likely work out the best. Good luck!
