Congrats on the new sweetie. She looks like she needs a little lov'n. Something I have no doubt you will provide.
Reference that Dodge V10, hmmm.......... The wife and I packed up the RV/Toyhauler with the fat gurl safely secured inside ( the Valkyrie ) being towed by my Dodge (Cummins powered). I'm willing to bet my fuel mileage was significantly better and I would almost guarantee I was pushing a lot more air. That RV has quite a bit of frontal area to push air and most likely weighed quite a bit more.
Oh yeah, I had a 4x4 Dodge Cummings in the prior Big Iron...LOVED it...on a standard tranny it would have done around 17-19mpg with this load. I put around 400,000 miles on it...much of that "moving heavy things about"...
It got killed here:
http://lifeisaroad.com/stories/2005/11/17/crunch.htmlThe V-10 in this 4x4 does 10mpg under pretty much all conditions and all loads...I can push it down to 9mpg if I *really* try...
For smooth, set ya back in your seat power it can't be beat...and it doesn't really care that there's a trailer back there...
