You would think Ford would offer the 6.7 Powerstroke on the F53 especially now that the tranny is the same used for the pickups. However as discussed before around here cost issues from having to do a diesel genny and probably heat issues at the doghouse. Probably cost an extra 15k I wonder how many would go for it? Would probably get 11-12 mpg and pull like a mule.
Got to wonder when Ford will replace the V10, either ecoboost or a more modern V8.
Ford really needs to put a rear track bar on at the factory and put better shocks on. With the 6-speed and for a few hundred $$$ folks would start wondering why a DP is 50k more.
Got the new PSI 8.8L gas engine could be real nice if it ever actually comes out. Spartan was showing a prototype in 2012, notice the air bag suspension:
Of course it will probably be as much a low end DP anyway.
I would like to see someone try a more aerodynamic design again like the Monaco Vesta, heck even older 80's and 90's gassers had better aerodynamics, thats where all our fuels going on these modern bricks.
