Meh. A "few". Like five. Maybe six. And not really for you and your RV.
Plus you won't need them.
An 80,000 lb. rig with relatively low air drag compared to your 8,000 lb. rig with relatively high air drag, like night and day.
All that said, I won't refute.
But towing near maximum with my Maverick without WDH leaves nothing else desirable for me. I don't view it as needing any improvement.
There's a million and one studies out there that the long-haul trucks LOSE Money by driving that fast. Yet some do it anyway.
You can't drive fast enough to fit in extra loads per week, so they are just burning more fuel for no good reason.
Not everyone got good grades in math I guess.
This isn't mine.
But I borrowed it and it tows behind the hybrid pretty well at 65 MPH on level highway.
Pulled it up some really steep residential roads at residential speeds.
Probably in excess of 12% hill for a couple of blocks. I even purposefully came to a dead stop on the big hill to see...
I tow heavy, but relatively short length trailer. ( 12 feet inside, like 15 with hitch).
I see absolutely no use for a WDH in this case. Being heavy, and I put a full 400 lb on the ball, I have had zero sway issues either. Lots of miles too.
I added airbags for leveling and a more comfortable...
I recently had some schooling in contract writing. Usually it is mutually agreeable to both sides to have as much grey area as practical.
Saying the bridge must be built by x date; or else, usually won't fly.
The wording will most likely be: "contractor shall make every reasonable effort to...
Depends on who you ask, what decade it was, and who was running the show at the time.
Bottom line: it is a "ROUGH" estimate; not an absolute. And there's literally thousands of variables.
I pull one like this but mine was custom made 1 foot taller to hold my side by side OHV with lights on the roof of the OHV.
Mine is 7x12x9 outside dimensions.
Hybrid strains a bit at 70 mph.
Too fast for me anyway.
I usually set cruise at 63-65 MPH and go for it hours on end.
Pulled a 11% back...
Ford says:
High Altitude Operation - Your vehicle may have reduced performance when operating at high altitudes and when heavily loaded or towing a trailer. While driving at elevation, in order to match driving performance as perceived at sea level, reduce GVWs and GCWs by 2% per 1,000 ft...
Everyone here please stop using the terms "safety" and "performance" interchangeably.
They are not the same thing.
Elevation does not change the safety.
Elevation changes performance.
Frontal area does not (tornado aside) change the safety.
Frontal area affects performance.
(And not always...
All it means is you can't drive 80 mph with higher frontal area.
Without doing the math 40 sq ft at 80 mph is going to take the same horsepower as 60 sq ft at 60 mph.
You get the idea.
I pull my blunt nose 63 sq ft trailer with my HYBRID and it does great at 65 mph.
And not a little bit. I...
This ☝ 100%
It will seem fine on day one.
It will be fine for a while.
In about a year, at most two, you'll have regrets. Those small details Ford knows about. Mom & pop shops may not.
