Older volvos?

I'm wanting to get a cheap areo truck and Volvo is one in the list. The trucks I have been looking at are late 90s to early 00s with 12.7 Detroit or 3406 cat.
I have heard some people say a lot of shops won't work on volvos but is that tue even if they don't have a Volvo engine in them? I don't wanna be stranded out in the middle of nowhere and need a part that I can't get for days.... Would his be a problem? Thanks
My other option are freightliner and kenworth t600 but they don't look as areodynamic and I hate the interiors.

 

That's what I was thinking. Thanks.

 

My max is 15k I found a 01 610 midroof sleeper with 12.7 Detroit 10 speed and papers for the rebuild that was done 250k ago for $12,000 it is in pretty good shape overall except the paint

 

Does anyone know what thy weigh? I've heard volvos and freightliners are some of the lightest class 8s but I can't find anything on that.
