Here's my two daily's and my service truck...
The ol 95 IDI F350 has probably hauled more shit to and from the farm and drug more stupid stuff home than I really care to think about. Have just about all the tools I'd ever need on/in that thing too. Air compressor, transfer tank, pretty much a full set of tools to fix about anything. 2.5 gallons of hydraulic oil, engine oil, and antifreeze too.
The 2000 Ford F-350 V10 with 5 speed manual is my winter rig and has about all those tools too. No transfer tank, but I do have a 12v compressor behind the rear seat and a 3 gallon reservoir tank under the cab and plumbed to some air outlets on either side of the flatbed. Not as fast as the gas compressor on the IDI but better than nothing when you need some air for a tire! Has a 9' flatbed on it and I want to keep it clear for hauling hay and feeding hay off the back of it for the cows in the fields during winter. Having a gas rig in the winter is nice for easy starting and fast warmup. It has also hauled a retarded amount of shit home too.
And then I got my service truck. 95 F-800 with a 5.9 cummins and 5 speed transmission and 2 speed rear. Has a digger derrick box on it. Torch, Miller Trailblazer 302 welder generator, 100' of leads, air compressor, still haven't fully stocked it with all the tools I want on there, but I have a shitload of space to fill still! Not even 100% done working on it yet, but other shit is more important to work on right now, and I'll get back to it someday. Need to get some more updated pictures of it sometime. I've used the crane to set I beams for my cousin on a remodeling project where a telehandler didn't have the reach, setting propane tanks, unloading a large 10' diameter tank off my trailer where my forklift didn't have the height to reach, and pulling irrigation wells. Also has a bucket to go on there too... Main reason I bought it was to drill post holes and set trusses for another building I plan on putting up someday. Plus the price was right.
