What's the best paying OO job?

I currently work for a Canadian based company. I get 90% of the gross revenue. Run whenever and wherever I want to as long as there is a load. Hometime whenever and how ever long I want. I usually run from Michigan to Texas and back every week. If I'm consistent with it and nothing bad happens then I can make 5-7k gross per week. On the lower end of that is the average though. I pay $506.25 for all my overhead weekly expenses, not including my $400 truck payment for a 2012 freightliner.(they only offer 2011-2013 freightliner and volvos) And not including fuel obviously. But the company is poorly managed and poorly run. So many problems here. I want to RIP their face off most days, but the money is good lol
Is there any other companies out there that have comparable pay and freedom but with better trucks? I've looked into Mercer and Landstar and it seems like I would take a huge pay cut going with them. Or should I just suck it up and stay where I am at?
This older truck is killing me on repairs and fuel especially. And they wont help me get into a brand new truck.

 

Well I just started as an OO here back in October. I've had to take a whole week off of work 3 seperate times already so I've been playing alot of catchup on bills. Plus I've had some costly repairs. I've also had some loads that made me wait a couple days to pickup or deliver which throws off my paycheck bc of their awful settlement policy. So about half of it has been due to me taking time off, but that IS my plan for now. Bust my ### and Save up and put a nice sized down payment on a new truck by the end of the year. I'm just sick of their incompetence and lack of driver appreciation here. So I'm just exploring my options here

 

That's my other option. After about April or May of 2020 I'll own this truck. So I could wait until then as well. But I would rather not bc I'm leaving money on the table by not having a newer truck. I've done the math and I would save way more money on fuel and repairs than I would lose on a higher truck payment. So again, im just exploring options. The company is based in Canada, with a US division but fully ran by the Canadian side. I live in Michigan and only run in the US. I'm not very mechanically inclined and most of my issues have been electronic so not even truck stops can fix it, it has needed a dealership. So doing repairs myself is very unlikely
Oh and we haul reefer trailers only here.

 

I agree but they have over 120 drivers I think and i think over 100 of them are OO's. So they cant be doing THAT bad financially. They just have idiots working there. And I cant understand half of em either

 

But the real question is, is there any other comparable companies out there? Or should I just suck it the F up and stay here and save up for a new truck? Lol
