going to post link so you can see. I think I may pass on the truck. Everyone says it’s priced to high got them down to 38.5 on a 2015 Pete 500 Hp with 13 speed. No apu or bunk heater to go with it. https://www.thepetestore.com/Peterbilt/model-579/113919
May have to leave truck where it’s at. People telling me it’s over price plus mileage also https://www.truckpaper.com/listings/trucks/for-sale/198128063/2015-peterbilt-579
Remove ramps and back under a dry van no problem. Nothing else needed. That is also a sliding 5th wheel so you will need to play with it under a load some to figure out the best position. Cant help you with the price questions... I'm not up on what trucks are going for these days.
Ive driven trucks with 3 times as many miles that ran excellent... Ot all depends on how well it was cared for amd maintained. At first glance that one looks to be in pretty good shape for being 5 years old and nearing 700k.
when I went in person to check it out everything seem fined and ready to go. I’m going to give it another day and come up with choice
