OK, a few points here that need to be carefully considered.
1 - There are probably some out there, but I don't know of any carriers that will allow anything substantial to be changed in their lease contracts. It's pretty much a take-it or leave-it kinda deal.
2 - Do you really think an LLC will protect your personal assets after a catastrophe? It won't. It will protect your assets in some areas, like protecting your assets from the liabilities of the business, where creditors cannot come after your personal assets for liabilities of the truck. However, if you have any of your personal assets tied in with the business in any way, like, oh, I dunno, a second mortgage on the home to buy the truck, then the LLC is worthless. Also, if one of your drivers gets into an accident and you get sued, it won't be the truck that will be sued, it'll be you, and the LLC won't help you one bit.
An LLC used to be a pretty solid asset protection strategy until a bankruptcy court in Colorado ruled that a debtor couldn’t protect personal assets in an LLC from a personal bankruptcy. Since then the floodgates have opened and the piercing of the corporate veil is easier and easier. The only decent personal asset protections you're going to get is if you go with a full blown corporation, and even then you're still screwed if you put up any personal assets, like a house, as collateral.
3 - Getting into this business as a fleet owner with no experience or knowledge of the industry is, bluntly put, pretty friggin' stupid. But doing so is pure Einstein-esque genius compared to someone getting into this business as a fleet owner with no experience and using their house for financing.
4 - You see this as an opportunity. But it's not, not at all, not if you have to finance your house, even a small line of credit, to enter into the business. What you see as an opportunity is, in reality, you trying to manufacture an opportunity that doesn't exist.
5 - If you want to dabble in this business and get through the bumps and bruises you're going to have to lose the delusions right quick. To wit:
"6) learn the system-- with understanding that there will be bumps and bruises in the 'learning curve' period, act upon 1-5 and buy first truck. use first 3-6 months to learn as problems arise, then see if project is viable. if so, repeat and build fleet."
The "Learning Curve" is a year, at a minimum, not 3-6 months. People have been telling you one year since you first posted on this matter, and after considerable comments that keep confirming that number, you boiled it all down to 3-6 months, and if it's viable then repeat and build the fleet?!?! OMG. That's utterly delusional, and I'm being kind.
It takes a year to learn the basics about this business, and that's if you're out there in the truck doing it. To sit at home as fleet owner, you'll be doing wonderfully if you can learn as much as 25% of what you need to know in the first year, in order to make informed decisions about what to do in the second year. And every year in the business brings with it brand new problems to deal with. The condition of the truck changes, rules and procedures at the carrier changes, education changes a lot, and drivers change. Every decision you or the drivers make change things. This is not an industry you can put on paper and manage it from paper. It's a constantly changing, fluid business that is managed literally from the seat of your pants, and unless you know all of the hundreds of possible ramifications of each and every decision, you'll almost certainly make the wrong one every time.
The biggest problem you're going to have is that you won't have the opportunity to talk with very many, if any, failed fleet owners, and most fleet owners are, in fact, failed fleet owners. Only a small percentage of them are successful. If you keep looking at that small pool of successful fleet owners, you will never learn the mistakes that the failed ones made. There was a time, just a few years ago, when one could enter into this business as an ignorant fleet owner and be successful in spite of their ignorance. The bumps and bruises and bad decisions of the learning curve didn't sink the business outright, and one could generally recover in time, because there was always plenty of freight for the recovery. But that was when the demand far outweighed the supply of trucks. That's not the case any more, and every decision becomes critical where the bumps and bruises of the learning curve can be fatal.
The only way to get around that is to enter into the business with as little risk as possible. At the top of the Do-Not-Risk List is tying your house to the truck. Next on the list is to have the smallest truck payment possible.
No amount of research will change the simple fact that you are getting into this business on the roll of the dice. If it were easy and enough research could make it a sure bet, then 70-80% of new fleet owners wouldn't be losing their shirts. Never gamble what you cannot afford to lose.
Like I said earlier, there are certain stereotypes in this business that we can see and recognize. And you're one of them. There's nothing inherently wrong in being a stereotype, as we all fit into one or another. The problem is, the stereotype you fall into is one that stereotypically fails. The odds of a fleet owner succeeding in this business is about 1 in 5, or about 20%. That's a fact. And those are people who know what they're doing. Coming into this with no real experience and with deluded expectations reduces your odds to just about the same as throwing snake eyes: 1 in 36, or about 2.78%. I'm not kidding.
You've got a shot at this if you already have a really good income and you're gonna try the expediting thing with your 'laying around' mad money and it's not that big a deal if you lose it. But if you expect things to work out like they do on paper, your chances drop dramatically to that roll of the dice odds. And if you put your house on the line to do it, you've got no shot at all. None. You're chances of succeeding with your house tied to this while not exactly zero, is about the same as rolling snake eyes twice in a row, which is 1-in-1296, or 0.0772%
Knowing all this, knowing all the advice that you have been given here, and choosing to ignore it, is the clearest indication of bad decision making that I know of, and if you power through and are determined to do it anyway, then your chances of success is throwing snake eyes three times in a row, which ain't good.
