^ 11mpg sounds pretty great to me, considering my 351W from the same era ('91) was lucky to get 10 and that was RC, 5sp with the same 3.54 highway gear.

 

Agreed, less worried about mpg - 'course wouldn't say no to better - but there are so many other costs associated with a truck and camper. No way around it vehicles are expensive.

 

I'd rather pay for truck fuel than not 'cause that means we're using it !

2017 Chevy Colorado Diesel w/ATC shell and gear 1200lbs additional.  I just did a trial run from my home at 7000ft. to Salt Lake City 4300ft. for a Costco run and some running around getting ready for a trip.  65 mph. on the x-way with a bit of city driving approx.. 100 total 23.9 mph...not bad...

I just completed a 2700 mile road trip and averaged 12.5 mpg.  Most of the miles were highway 50-65mph, with a chunk of freeway 60-75mph and a bit of 4wd.  2012 Tundra 5.7 DC w/ Sun Valley Apache 6.5. I notice much more appetizing instant mpg readings if I stay under 60mph and under 2k rpms (as someone else mentioned here).  I average 16mpg without my camper on.

Re: MPG and costs and safety

 

I have a trip planned in May from Calgary to the Burr Trail in Utah.  So plenty of 70+ mph highway on the way down, and then lots of 4x4 and gravel road once I am there.

 

I expect to get 12 mpg overall with my rig, which is a 2002 ¾ ton GMC with a big gas engine and a Hawk on the back, plus me and my spouse. 

 

I estimated gas costs at $3.50/USgal.  Cost of gas for the trip works out to $849.

 

I do maybe 2 such trips a year, plus in between some shorter trips.  Total mileage per year is around  8000 miles per year.  That’s about $2400 in gas.  If I got 2x that (in a newer diesel Colorado for example) I would save $1200 in gas per year.

 

If I sold my truck today I could get $8k for it (maybe… Canadian funny money)

 

I’m seeing 2017 Colorado’s going for about $45K up here.  The difference is $37k.  Saving $1200/year would mean my break even would be 30.8 years.  

 

I think I will keep my gas guzzler. 

 

And my Hawk which would overload the Colorado.

Vic, my declaration about my bare bonz Colorado set-up wasn't to dis big gassers as I own one myself a 2004 Chevy Silverado Crew Cab w/8ft bed.  I wanted the mid size to fit in the garage and as a summer daily driver/small camper set-up with enough oomph to haul my 27' travel trailer.  Since I also need a big truck I also wanted  to stretch the time left on the Silverado as it would be about $55,000 to replace

Vic....that is another very good point....if you get "lousy gas mileage" (that being over 10 but under 16 MPG) on your "old" truck but it has years of life left and many miles to go then you aren't making monthly payments or paying higher auto insurance payments.

No dis perceived nor intended.  Your Colorado example was a good one... and about the only one I would consider switching to.  So, that's why I used it.  ;-)

BTW the Silverado set-up gets 10 mpg give or take 70+ on the x-way.

Remember that if you S-L-O-W D-O-W-N to 60-65 MPH or even a bit less...one most drives, that only adds a few minutes to about an hour to each days' drive if it's an all-day one.....its amazing how much more MPG you get by doing that.

 

I don't drive like an Old Man even though I am, but at about 65 MPH I'm happy to get where I'm going and maybe save a few bucks along the way....no offense intended but towing at 70-75 MPH seems to be pushing the envelope a bit for me. That includes a second vehicle, a boat or a trailer of any type. Once you go past a semi or two going the other way on a two-lane road and he's doing 65 and you are doing 70-75 MPH and your rig stars weaving around due to the air he's pushing you might find you are headed for a ditch. I've seen guys with a camper towing a boat in front of me do exactly that and it scares the pants off you until you regain control...or don't.

 

Just sayin'.....

I have not noticed anyone mentioning if they use cruise control and if they find it impacts mpg. Don't know if my CC is faulty(2008 Tacoma), but it seems like using CC costs me about 2 mpg highway driving and I drive 60-65 mph. When climbing a grade it does not adjust quickly when the road levels out so truck runs up to about 5 mph over the preset speed for a few seconds then adjusts. If I switch if off just before  the top of a hill and then back on when road becomes level, I do a little better and the CC then costs me only 1 mpg, but that is a PITA so unless I am on a long stretch of level road I just leave the CC off.
