Two Questions..

[Heritageclassic07]

First Question- What service manuals do you guys prefer (2007 yukon XL)?
I really prefer a book type, not a CD or PDF based manual.

Secon Question - What are the airbag system that you guys recommend adding for towing, i read a post about them somewhere i just cant seem to find the post.

Thanks.

i can also view the whole thing on my laptop, tablet, and or iphone.

I have a LTZ, it has built in airbags, so I do not know. we put firestone in my dad's excursion.
