Bottomland, Bob is correct. I am on my second t/c with a Volvo chassis. I cannot give you any information regarding the Freightliner since I have never driven one. One of the things I didn't like about the Freightliner was the split windshield, I think the Volvo cab is a bit larger with less gauges and more computer read outs. Cab noise, I can't say either is louder than another for the very reason I have not been in a Freightliner but I feel the noise level in the two Volvos allows me to talk to the wife at a rather normal voice level.
I think the Volvo takes longer to get up to speed over the Freightliners because of it runs thru the gears but that may just be me pampering my t/c.
With that said. I like what I have, plenty of power, nice ride and everything Volvo..
