Just a few things-
1. buy a used bare-bones work truck, everything manual, and simple. Here's an example. I bought a used 2wd chev 2500 6 years ago, it had nearly 80,000 miles but I picked it up for $4k, I have replaced the tranny, brake parts, muffler and battery, totaling about $2,250. So I'm into it $6,250. (not including oil changes and tires which all vehicles go through) That is less than 9 months of your $700/mo payment, for 6+ years and 80,000 miles of use.
2. If you are putting 70 gallons/week into your diesel- then you will have some serious routing problems. That's about 1,000 miles/week, which translates to about 25 hrs of windshield time. 1 thing that I learn more and more;
3. Just get what you actually need. If your props aren't that big, then a 36" WB will get you started. For bigger props a 52" WB is a decent start.
Good luck- we're not trying to be rude, but it's a lot better to have someone tell you these things, than to learn them the hard way as most of us did.
