@Siinman, good looking setup. I would recommend getting a deer basher as soon as you can afford to. I don't recommend them for deer as much as idiot drivers, especially in truck stop lots and tight docks. I don't want to ever drive a truck again without one.
Well got loaded with a 45K load of water from MO to AR was 6.7 on that trip. Lot of hills and some back roads. TN to WA 12K load was doing real good at 8.6 until past MO and hit wind from hell for 1.5 days. Took me down to 7.3 doing speed limit up to 70 MPH. Finished the trip off to deliver in the morning at 8.1. Did 62 the last day of driving since half of it was in WA anyways at 60. Think I could have got close to 9MPG if not for that terrible wind. Over all so far I am at 7.9MPG for total trip. Funny thing about the wind is I can barely feel it when driving. If I was in my other truck I would had been moving all over the place and wore down. This truck drives live a dream. On another note it did have a problem pop up yesterday and it is a known issue with the Volvos. The CAC cold side hose clamp gave out. Lucky I was close to billings and called the guy I used last year. He had a couple clamps on hand and came out and knocked that out in 30 minutes. I had forgot to order the clamps when I got the truck. Had it in my to do list of things to buy and just for got about them. I got lucky and had this rubber tape that works perfect for Hoses. It will turn to rubber after you wrap the hose and it heats up. Love that stuff. Here it the tape https://www.amazon.com/gp/product/B00AEBKYPG/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1
There is no proper way to test them correctly.. Unless you pull the exact same load on the exact same conditions on the exact same route.. when your trying to get a accurate comparison.. especially when your talking a gain of .01 or even .03 mpg.. the terrain or the wind alone can change the out come of tests more than that..
My company did that - closed loop drivers hauling the same loads every day. Wheel covers passed into general fleet testing, trailer tails didn't.
Took me 30,000 miles for mine to pay for themselves.... and that was not the cheap one's like these but the pricey ones from real wheels
I had a team deadacated run Laredo to Detroit and back 39,900lb up and 7,000 down... 90 avg before and 90 avg after showed .23 mpg gain...
Yep this is a known issue with all new Volvos. They should have this on a recall but wont do it. Everyone seems to have these issues with these clamps.
