computer idiot here!

Hello to all,
As I began, I am a computer idiot and doing this is foriegn to me. I only logged to gather info about mechanical soundness of the newer aerodynamic rigs! As an old cabover driver, I am no longer hauling hay, livestock or farm equipment. I haven't hauled otr since college two thousand years ago. At 45, I am out of kids at home and Momma wants to come along.
I've looked at the T700, Cascadia and the like. I have read the Cascadia has electronics problems as well as fitment issues. Obviously my career has never seen above 5mpg in my co Int. Estetics and sleepers don't matter as much as function and durability. Of course Ma wants to bring her cats along and they'll do fine as long as she has a good sized sleeper and comfortable chair.
Any experience with these newer wider aerodynamic rigs will be appreciated, especially from traveling couples! I am not looking for slams about body styles or appearances, function and servicability!
Thank You
LGE

 

Thank You Dognot!
I have been swapping emails with two different corp. sales reps. I treat them like my Army recruiter; "believe none of what they say and half of what they do"!
The International guy is selling their non-DEF using engines and Freightliner sells their satalite assist systems.
