First Time Ordering New Rig - Advice?

So aim for around 1500? Yeah I was slightly confused when a few reps have said they like to run low on the revs but almost every driver recommends running a little higher. Fuel economy isn’t really my BIGGEST goal, but if I can move some things around and help myself without risking the motor then I’ll do whatever it takes. Thank you.

 

Don’t know why but I completely forgot my 800 at work had that exact issue, I will ask the mechanic who replaced it for what he did. Seemed to me he replaced just about everything as they even wiped smoother and slower.

 

What’s the difference in tire wear between 65-70-75? Do you guys usually run as hard as you can within the speed limit or sit in your own sweet spots?
