Your thoughts on a volvo?

The 500 used to get 6.5 from colorado to california. Running east coast gets 6.6-6.7 cruise at 67 (limited at 70) and Idling for A/C. The 425 limited at 85 was at 6.3, at 70mph gets 6.7 and now with apu gets 7.0.

I like the 500 more, the fuel difference is not much but the truck feels like it doesn’t struggle as much.

 

I have a 15' 780 D13 with iShift. It came with 425/1550 and got about 8 mpg. I had it turned up to 500/1750 and had the ishift set to 'progressive shifting' and it made a big difference. MUCH better on hills. Before it would not downshift on hills until it dropped to 10k RPM on the nose and I was always losing too much momentum. A lot better with the upgrade and I don't see a difference in fuel economy. I get 7-8 pulling as light of loads as I can find and I drive 70+ if that's the speed limit. I have an APU and try not to idle.

 

The truck had a carrier comfort pro (I think 6022, and older model) needed some work, spent about $1200 on new generator and did a tune up and runs great. I was considering an electric (chil-e) for the other truck since I don’t want to give up the big fuel tanks.

 

Only good Volvo is old Volvo truck.

 

That sounds great, I am happy with my fuel economy if it can get better is even better. What APU do you have?

 

Do not spend money on an electric apu. They're as good as having nothing. Find a way to retrofit it with the big tanks or downsize, it is worth it.

Carrier is louder, shakes more etc but works.

Thermoking is quieter and you don't feel it.

I guess it would come to price.

 

I run a 2016 Volvo with the D13 and iShift... I run from the Rockies to the Mid-west and back every week. East bound I'm always 79k+, west bound I'm anywhere from 66k to 80k. I get about 7.3 mpg, and I idle almost all the time... Sometimes this truck doesn't shut off for 7 days when it is really hot weather.
