Front nose design and stability and gas mileage?

[MookieKat]

I am seeing that the newer nose design is rounded whereas the older ones are big and flat.

Has anyone hauled both types with the same TV and seen a difference in stability or gas mileage?

I lost approximately 1 mpg when I moved from a Canyon Trail 27FREL to a Tradition 360 RSS.

The Canyon Trail did have a more aerodynamic front, and was quite a bit lighter, but I much prefer the additional interior space provided by the flatter front area.

YMMV...

I pulled a flat front 5th wheel toy hauler (which was like pulling a parachute)with my Dodge diesel, and now pull a Keystone Outback that is heavier and longer and has the rounded front with the same truck...I do get better fuel mileage and the overall handling is better, fuel mileage got better by 2 or 3 mpg...I didn't change for the fuel mileage, but I'll take what I can get.

Perhaps its easily discounted because industry drivers do more miles in a 2 week period then I do in a year ,so ya I dont care about 'aero' that has a almost infinate payback.

If the large fleets see value, then I can't understand why it's so easily discounted here. 1 more mile per gallon can easily mean a 10% discount in fuel costs for a trip given that most rigs achieve around 10 mpg towing. So personally, I am considering a 5th because of the increased Aero (especially with newer cap designs), More room for a given length, ease of hookup and disconnect and a shorter overall foot-print when on the road.

Thank you!!

Yes, we don't buy 5th wheels to save gas but I'll take every opportunity I can to save gas if there's no significant trade-off. For full-timers, gas cost is significant. 10% gas cost reduction is always welcome.

I mentioned Lifestyle and DRVs before because they appear to have rather flat looking fronts which does concern me. Its not enough to take them off my candidate list but those are definitely negative factors. Excel Winslows seems to be a bit more rounded...

That is amazing!!

Every 'hot shot er' i have asked said the same -5ers beat TT s.

I would certainly agree with that.

Many here will remember the Titanium models of fifth wheels, made by Glendale in Canada. Aerodynamic also.

Would either DRVs or Lifestyle 5th wheels considered to have flat fronts?

I guess that most of us would not buy an RV totally for gas mileage either. I have another friend that says "when it needs fuel, I fill up", but I have to keep within a budget to do what I want to do. I think about fuel mileage more when I'm on a trip with the camper than when driving the car. By doing a few small things, I was able to get my mileage from 9 to about 9.9 mpg. It doesn't sound like much, but a trip a couple of years ago that cost about $6000 in fuel ended up being a savings of about $600 of what it would have cost. $600 paid for about 3 weeks of camping for me.

Fuel mileage while pulling a 5 ton box down the road. Ha ha

I average around 12.2 to 12.5 MPG with a round corner 6+ ton box!
