By the way, when I was just starting out, I looked at every penny and found it "slightly" cheaper to fly (and/or sometimes drive!) out and pick up the load myself.
More than once, I drove from Las Vegas to Denver, Phoenix, LA..... those 'road trip' days were fun, but a LOT of driving! You have to really be counting the pennies (which I was) and figuring your time was worth 'nothing' (which it isn't, but when all you have going is that load, it becomes the most important thing in the world!).
SAFETY DISCLAIMER - NEVER TRY THIS YOURSELF!!!
I recall one of the early, 'desperate' days when I rented a truck in Vegas, leaving at 8:30 am, driving to Denver (a 10 hour drive in a fast car - no so quick in a truck!) and getting in just around 10 PM - wondering if I should just sleep in the truck to save some bucks..... but, I got a hotel room (HIGHLY suggest you take care of your body first!)... At 7:30, I was at the pick up location, got loaded by 9 and was back in Vegas that night by 11 PM (had to stop a few times on the road to grab a short nap!)
Another one, I was visiting my family in OK and a load came up in Wichita, KS and another nice one in Manhattan, KS, plus some were coming up in Denver, OKC and Dallas. I arranged for a friend to work my shop in Vegas and stayed with family until I won the KS loads and waited to see about which 'route' to take back - through Denver, OKC or Dallas (hoping I would not win all three!
Wound up all I got was the KS ones (which was ok, but not great - I much prefer to have a LOT of stuff to go through, you never know what might work and what won't!). Went to rent the truck and all they had was a 24 ft-er! So, I took off from Tulsa and up to Wichita, then Manhattan and "the long and winding road" cutting across KS in a southwesterly direction to catch I-40....... That trip took me just over 2 days of super-hard driving and cost a small fortune (those trucks sure can eat some gas!) - so much out-of-pocket that I slept in the truck and wound up cashless when I got home! The good news is that, even with the small load (less than 5 feet taken up in the truck - very loosely loaded!) and all the expenses, I made about $4000 on that run - took several months to sell the stuff off, but well worth it!
I will finish this up with "those were the days" - or, so it seems...... So many people are now bidding on gov't auctions that they are really difficult to find a good one that you can buy at a reasonable price and make any money. Note that $4K is a nice day, but it was not made in one day - I had to outlay cash, do a lot of work advertising, cleaning, etc. and store the stuff as well until it sold, plus all the labor involved in all the steps. You have to figure all that in - BEFORE you bid!
I don't want to discourage you in any way from bidding on gov't stuff - deals are still out there, just not "good" ones being as plentiful as they were even 5 years ago (and even then, they were getting 'slim' at times). Best thing is just like doing the refining side - RESEARCH and be sure of the steps before you get into it (and also have a decent 'Plan B'!)
