Brand New semi trailer final cost

Does anyone have any resources ( or just the right terminology for google search) to find out what my total final cost will be on purchasing a new semi. By this I mean added items i will be paying for, not actual dollar amounts. I know that depends on other factors. I would like to research ahead of time what i actually need to pay for and what is unnecessary or what to be careful of.
I watched a video of a team couple that bought new at $156,000 gave $35,000 down. Amount went up to just shy of $200,000 and at the end had a finance balance of $178,000.

Im not sure if this sounds right or not, appreciate any info

 

Thank you, I will definitely check into the FET charge

 

Thank you everyone for your info, looks like we have a long wait, can’t even reserve our truck for a few more weeks. After that, we still have to wait until Dec/Jan for the 2023 models because all the 2022s are sold out ( Kenworth, Peterbilt, Volvo).
