I'm just almost certain that a bank would tell me I don't need a Ram 2500 to drive to work.
I guess my big thing now is do I apply for a personal car loan or a business loan? Also do I need to register the truck in the business name? I never get to go anywhere so I thought if I could do some travelling and get paid to pick up loads on the way it could be just what I need.
This is way more complicated then I can fully go into right now but I'll share a few basics. First off >90% of the folks driving SuperDuty/Heavy Duty pickups have no reason to other than they like them. Banks don't care what you buy as long as you can pay them back. Most lenders will approve you for a loan amount and APR based on your credit worthiness and income. If those are sufficient they could care less what vehicle you purchase. If your credit score and/or income are on the lower end of the scale they might take a small interest in the vehicle but again it will be more in the direction of why are you looking to buy a $40k vehicle when your income is only $XXk per year.
The second part is even trickier but can save you a lot of money if you do it right. You definitely want the truck in the business name so you can write off most or all of the expenses to reduce your tax liability. Gas, tires, insurance, maint, even some or all of the payment depending on how you use it. The best part is you don't even have to be profitable the first few years to take advantage of this.
There really is much more to it so I would dig around. Your best bet is to find a savvy small business owner (or two) in your town. He or she will be able to give you the ins and outs better. A solid accountant is also helpful but can be costly so start with the small business owner.
