Just my .02 cents worth, take it for what it's worth. First and foremost, I can't stand RHD rigs. I regularly have co-pilots to share long distant driving with and there's no way I'd be able to catch a wink if I handed the reigns over to a "non RHD operator". I also have different co-drivers so a RHD wouldn't work for me. Drive throughs and ATM machines would be hell I'd imagine.
As far as the diesel vs gas debate, meh. A baby DuraMax in my 80 with a 6l80E tranny would be nice but a tired old 1HD-T, not so much. Besides bringing an old Toyota diesel engine up to spec and all the associated $$$ that goes along with it, the additional cost at the fuel pump wouldn't add up for me. But, I know few folks who "loves the smell of burning oil" in the morning!
I don't drive 65mpg and enjoy the scenery on the right hand lane like lots of folks do. Yeah, I know, I know. It's the "journey", not the "destination" <roll eyes>. Maybe when I'm retired, I can take my slow ass time getting around to places. But for now, I like to haul ass to the trailhead after work on Friday, then haul ass home on Sunday. My middle school age daughter practically leaps through the window like the Duke boys while I roll through the school parking lot as we head out of Dodge.
You'd be hard pressed to get 20 mpg on a 1HD-T engine at 80 mph and god forbid your elevation is changing drastically. As far as I know, the 1HZ and 1HD series rigs don't compensate for the barometric pressures but I'm not certain. While 4-wheeling all day in 4low, oh yeah, the diesel wins hands down. They just sip diesel while the petrol still guzzles.
Bottom line is if you have an itch, go ahead and scratch it. It doesn't need to be justified.
ps my co-worker bought a Colorado with the baby Dmax. Now, if chevy would be so kind as to produce a six banger TDi........
