Perhaps your research has led you to the fact that the Leaf is a great town car but a rather poor long distance car. If you keep trying to use it for long distances in the summer with high heat levels, you'll likely damage the battery which is a huge expense. Having discovered these issues, perhaps it's time to trade up to a Tesla or other vehicle with active battery cooling that would better meet your needs?
That’s…horrifying… global warming could eat electrics…
And eat ICE.
(that makes a pun too, I.C.E., global warming, haha) There is a portion of the Appalachian Mountains where the road ways up have many "pull over" spots for over-heating vehicles that climb the mountain. The first time I was driving through (in cool fall weather), I thought it seemed silly to have so many, like every 1/10th of a mile seemed to have one all the way up the mountains. I made the same trip through the next summer when temperatures were +95F and sure enough. The entire road was a mess of over-heating vehicles. Cars, trucks, RVs, basically if anything was towing a trailer, it was over-heating and parked on the side to cool down. 
During that same time, I was towing a trailer with close to 800 lbs of metal tower structural pieces and never had a single issue with the Leaf, even with the AC going because it was sooo hot that day. I did manage to bring the battery temperature up 1 bar past the "middle" point on the trip, but that was about it. 
Indeed. If you use the LEAF for what it is best suited, high battery temperatures will be much less of a threat - and the vehicle will serve you well for more years and miles.
Yes, I get it, and that's what I originally bought it for. But circumstances have changed so I may just need to find another option. I actually have an old Subaru which I normally use for longer trips, but was hoping this could cover it at least some of the time. Middle of the summer in the south is probably not helping. I've actually been trying to hold out for an EV with the cargo space of the Outback, not seeing one yet.
Drafting. Dangerous ‘cause you have to get so close you can’t brake. Truckers hate it. “Excuse me, I’d like to threaten your life for ¢50”. If they’re dead heading they stop faster than just about anything. Airbrakes and 18 wheels 4.x times the patch your wheels have. If they’re deadheading they don’t weigh 4 times what you do. A truck with no trailer on the back has performance not that different in some ways from an F1 car. Fully loaded trailer not so much. They race em when trucking gets awful. Thats part of what CB radios were/are for. Finding out how heavy a rig is can tell you how fast it can stop. They do it but the guy behind is lighter than the guy in front. Use to be 5 or 6 of em doing it at a time. All organized by weight. Haven’t seen that in a long time. If you do it you need to have a CB radio in your car and know what your 60-0 is for safety.
What was your 60-0 length at the time out of curiosity?
I don't understand what you are asking? I was about 60' overall, 48' trailer, Single bunk cabover tractor.
I frequently take 150 mile trips, driving mostly 65 mph on the Maine Turnpike (I-95) with a quick dc charge along the way. Summer temps lately around 80°. My temp gauge has never gone above halfway. I never gave it another thought until I read these posts. I guess I'm just lucky.
Maybe they don’t pay attention to that any more now that convoys aren’t so much of a thing. My memory was that total weight affected stopping distance. You were at max load so it would have been your max stopping distance. Basically my inner 12 year old fanboied for a second. My inner 12 year old lives in 1979 though.
lol. Dare I say I smell what you’re cooking?Ooh! Water dripping in close proximity to high voltage. What could possibly go wrong?
If done very carefully and cleverly it could work well I suppose.
At 25 MPH and over 400hp working to drag it, I'd be more worried about rolling backwards before I could get off the throttle and on the brake.
Thanks, will check it out. I was just wondering, how much elevation changes (lots of climbing) had to do with temperature during Asheville trip. Also, a later trip probably complicated with high freeway speeds and high temps. Annoyingly difficult to avoid highways with 70mph limits with some of this, at least typical navigation isnt much help.
