OK. I didn't know if you had been to the Thor forum, or were aware of it.
I'm not familiar with the V 10 triton gas Miramar 34.2, so I have no idea the size.
I towed a Jeep wrangler with a small class c that had the V 10. I couldn't really tell it was back there.
My suggestion would be if you already own both rigs--try it. Then you will know from your own first hand experience. The V10 is quite a work horse.
