I will definitely be watching this thread, I'm just beginning to think about shopping for a new truck, doing very casual research now. I'm leaning towards a '15.

Lots of missing info we need. First off, what gross weights do you expect? What speed to you cruise at? Are you specing to burn op the hills at 70 mph or do you care more about mpg and saving money? Those 2 options have totally different specs. Would you consider Super Singles to save fuel? Would you consider a 6x2 with a locking dif to save fuel? (6x4 requires more power to turn, if only 1 axle is powered, you save fuel but loos some traction in snow)
Auto or manual....wow, you just handed a serial killer a loaded gun lol. Search the forum for that answer. there are several threads on that one, although the Volvo I-shift is nice. -

Well to select your rear end use eaton's calculator. http://www.eaton.com/ecm/groups/public/@pub/@eaton/@roadranger/documents/content/ct_062746.swf I recomend 2.64...will explain
Personally I'd spec your truck with the overdrive ishift, BUT spec the rear so you hit 68 in direct gear (11th http://www.volvotrucks.com/SiteColl...ts/Powertrain/i-shift_spec_sheet_ATO2612D.pdf)
This will allow a little better mpg while in 11th do to less mechanical loss in a 1:1 ratio. If you need to go 80 you will still have a whole extra gear (12th) to do it. Alternatively you could go with the direct drive ishift, but then you don't have the extra gear when you need it. Depends on how often you plan on speeding.
Now if you want best mpg, spec the truck for 65, not 68 and slow down a bit. Since speed and power seem more important, lets try and increase mpg without sacrificing power. Since your not driving in snow much I'd highly recommend super singles. These can save you .5 mpg which is a nice chunk of change for not changing your driving habits. yes if you blow one your stuck, but how often do you blow one? Theres thread on the pros and cons if you want to read about um. I like um.
Idealy you also can go with only one powered axle. By turning one dif and having one tag (dead axle) you reduce mechanical resistance. Also you can put a trailer tire on the tag axle since it wont be subjected to torque. trailer tires have less resistance. This will be a special item and will probably cost a few more grand but will easily pay for itself. Even if you go with 2 diffs and 2 powered axles like a normal truck, i recommend the singles.
Xone line energy D are best for drives, and Xone line energy T are best for trailer or tag axles. Now if you planned to do flatbed and were off roading i might change my recommendation, but your gonna try to stay on the road arnt you? lol Wheelbase shouldn't be longer than it has to be for your reefer to fit behind you with the 5th slid all the way forward. It will varry based on sleeper length but no need to get longer then you need. Volvo should be able to recommend wheelbase length.
As for hp, I'd recommend the highest horse you can get in a d13. 500 horse should be enough 98% of the time and the d16 is a lot more money and weight. last time i checked, you seemed a little heavy so going with the lighter motor should help. As for rear end, 2.64 will get you near 68 @ 1500 rpms in 12th leaving you a whole nother gear to go fast when you need to. -
may want to add air tabs, they are ugly, but cheap and increase mpg without changing driving habits. Also get yourself side skirts on the truck. A bunk heater is also a must. Yes i know you live in florida, but you may take the cold route sometimes. They burn almost no fuel and keep you as warm as you want. No need to idle. You may want to consider an apu for air cond.

If solo consider 630 for less weight, not sure what You save thought...

heres the motor specs

You can get the ego tourq in 455 or 500. up to 1750 on the 445 and 1850 on the 500. Do you need 500? No! but your also talking about going 68 all the time and possibly hills. Aslong as you control your right foot they get the same mpg. but yea, if you use that extra 45 horse mpg will drop.
Not sure on reefer weight....i know empty van is roughly 12000-15000 depending on a brand, age, spec, etc. the d13 vs the d16 will save a few poounds.. Volvos are heavy tho. Noway around that if you want a volovo
