What are the best truck rental companies for a DITY move and what advice would you have for someone doing a DITY move?

if you don't mind packing yourself or getting some of your buddies or Platoon function such as free food/barbecue lol then this what I used. https://www.upack.com/abf

They drop a small semi trailer in a location of your choosing. You are minimally charged for I think 19 ft. If you need more you use it and they charge extra per foot. The key is to stack all the way to the ceiling. At the end you block and braced, with the equipment they provide and you put a lock on the brace. The truck will then rent the little bit of space left (if any) for commercial companies like Best Buy. Another advice get it on like a Thursday, they wont pick it up on the weekend so you get an additional day free. I did this with very little help and I was tired! If you can get some help it won't be so bad.
The trucks ships the trailer to a hub in your destination location till your ready. When your ready you set a date and you get your trailer with three days to unload it. If you need more days to load or unload you can but they charge for. The link I included is the website I'm sure you can find all the info you need on it. O and the company provides you the weight tickets, empty and full.

Just remember follow Regulations! No cement or concrete blocks to increase your weight! I heard a story of someone buying bags of cement from Lowes to increase weight then returned the bags. When he turned his paperwork in to get paid from the Army he accidentally turned that receipt in. Needless to say he lost his rank.

SSG (Join to see) I can't remember which company I used for my DITY moves, all I could think of is search until you find one that fits your needs. My advice is, if you want to make money in that DITY move, ensure that you use every last pound of your limit, and don't forget to do your empty and full weigh ins and keep those receipts.

In my experience Penske is the way to go. Cheaper, better gas mileage, newer trucks.
