4 Lane 400 series hi-ways I do 100 KPH. Right lane, let them pass.

We're about the same except 90 in an 80 (100k on the 400's and the not so "Quick En Easy"). Most of the roads we travel are two laners anyway, enjoy the ride and arrive relaxed.

10-12mpg (imperial) at 100kph averaged over last 4 years with our 35', manually calculated.

Ok, looks like most folks drive their RVs around 65. On a 75mph interstate that's only 10 below most traffic, 20 below traffic having a TX or CA plate
My question - do folks going 55 really feel safer driving 20-25mph slower than the majority of the traffic?
If the traffic is light, not so bad, but in heavy traffic, going that much slower just seems to be a rolling roadblock.
Just curious.

We cruise at 65 on interstates and slower on US routes. It's been an adjustment to the learning curve to go slower.

Well that’s why they put that skinny pedal on the right in every one of them and don’t have a switch for towing at a set speed. I know from experience an increase in speed of just 3 mph from 62 to 65 in the trucks we drove made a substantial difference in fuel economy and tire and vehicle wear. It’s just my choice to do 60-65 depending on the circumstances not a limit of my equipment. I’d rather ride than change tires.

I usually run 72 mph. I will temporarily exceed that if there is lots of slow traffic in the right lane. I have Goodyear Endurance tires and pull my Superlite 5th wheel with a F250. I get better fuel mileage when I run 65mph, I’m not retired yet so we usually have limited time, so I try to get there.

I aim for 65+/-2. If I'm on a 3 lane highway, I'm in the middle....folks can pass on either side....I avoid the right lane because too many idiots have to get ahead of us when entering the highway......I hate losing "Uncle MO" because they just have to get ahead of us.

I haven't seen too many 75MPH areas.

65 better fuel mileage

[RetiredArmy]

I always drive the posted limit and watch everyone go around

[Roberte52]

I try to go with the flow of traffic in the right hand lane.

I set my cruise on 65 doesn’t matter if Speed limit is higher, it is much safer and better on the tires, if your in that big of a hurry to go faster, park the camper and get on an airplane!

[Fmueller]

I always try to keep in below 65. RV tires are for load not for speed. Blow outs are dangerous.

[windowman]

The slower the better fuel mileage and more control agreed. Have been on 95 at times when at 75mph you are an impediment to traffic flow

[Don Jones]

I have placed myself on a 65 mph limit, better fuel mileage and easier on tires.I have a TPM and they will run about 8 degrees cooler also

I may be unusual, but I stay 55-60 mph in the right-hand lane for a few reasons: It saves me gas money; it's easier on the tires (I currently have those dang Chinese tire bombs on my Ladybug trailer but will be changing them out before my next trip!); I realize that the emergency stopping time with pulling a trailer may take longer than without one; and with being in the right-hand lane, it allows all the speed demons and 18 wheelers the clear path to fly right on by me! The drive is easy staying at those speeds in the right-hand lane.

Max of 65 on really smooth roads. 55 max when it gets rough. Had a blowout on a smooth road (I-10) and repairs to the 5th wheel weren't terrible, but will still be pricey to fix.

I typically run at 65-70, mostly to try and help with the fuel economy on my Ram 6.4 Hemi. I’m trading up to the Cummins this spring and might bump the speeds to 70-75, under the right conditions, but I’m not usually in such a hurry that I need to run down the highway as fast as I can.

DING DING DING. Winner winner chicken dinner!

Fuel mileage aside (for as I stated in a previous post I didn't buy and F350 for economy), driving 65 I don't have to be a regular lane jockey. We bought an RV for the journey and not just the destination. If I wanted to get someone place fast, I would take a plane. But when we all hop in the truck and I hit that start button, vacation and relaxation begins. And so being in that right lane with cruise on and letting people pass me allows for less stress (plus it's safer and I get some better fuel mileage).

My sweet spot is 1800 rpm which is 63-64 mph. Always hoping for a stiff tail-wind :-)

[Don Jones]

Adding also, I am 74 years old, these speed demons that have to blow by you, one day will reach my age if their lucky and wonder where all that time went so quickly. That’s my main reason for slowing down to smell the roses and enjoy the time left I have.
Y’all have wonderful camping and making memories.
