Making the change from diesel back to gas 2014 Itasca

Pulled the Grapevine many times with my 2000 V-10 at 25,000 Combined Gross Wt. Newer V-10's are more powerful. If your trailer puts you near the CGW rating you should have a transmission temperature gauge. If the tranny temp gets too high you will need to use a lower gear and give up a bit of climbing speed. The V-10 absolutely will climb any hill - gear, speed, and engine noise will vary - well the engine rpm necessary to get horsepower will always produce lots of noise.
