Yes heat stroke is nothing to mess with. Once you have had a heat exhaustion or heat stroke episode you will be more susceptible in the future unless you get cooled down quickly.
Heat exhaustion is the precursor to heatstroke and is a direct result of the body overheating.
Heat exhaustion is identifiable by heavy sweating, rapid pulse, dizziness, fatigue, cool, moist skin with goose bumps when in the heat, muscle cramps, nausea and headache.
These symptoms may develop over time or come on suddenly, especially during or following periods of prolonged exercise. Heatstroke is the most severe heat-related illness and, without emergency treatment, it can lead to death. It results when your body temperature rises to 104 degrees Fahrenheit or higher. In addition to high body temperature, the symptoms of heatstroke include altered mental state or behavior, nausea and vomiting, flushed skin, rapid breathing and racing heart rate. Generally with heat exhaustion, a patient is sweating a lot, whereas with heat stroke, they’ve stopped sweating and are actually dry. It’s a good rule of thumb but isn’t always true
At the same time, the OP's husband is into fitness and is a hiker, and they're both in their 20's. If I can do it in my early 60's, they can do it as long as they take precautions. I get it that they're from the UK where the sorts of temps/aridness they'd experience would be a new thing so...
To be fair, Grandma, when was the last time you did an 11+ miler in 90 to100-degree heat or at all anywhere?

It isn't about me or what I have done. That is not in the least relevant.
Do you not remember the marathon runner who staggered to the finish of the marathon with severe signs of heat exhaustion? That woman was fit and young and trained, but still had a problem.
The temperature was 86 deg F which is not that hot. And some of her problem was that the rules did not allow medical assistence without disqualification and allowed only 5 water stops and she missed one. The rules have been changed as a result.
It has a lot to do with acclimatization. People who work in blast furnaces, or other hot environments get acclimatized to the heat, but when they go on vacation, they lose their adaptive ability for the heat and have to work into it again.
I was a workplace health inspector for 14 years and I investigated several deaths from heat stroke and have done numerous inspections and evaluations for heat stress and also did training of employees so that they could intervene appropriately, as when someone is suffering from heat exhaustion the suffering person may not recognize the problem themselves. If you know the symptoms or have someone with you who knows and can provide appropriate treatment-intervention, then go ahead. Just be careful and don't be too macho to admit that you might have to turn back.

But Grandma, running a marathon is different than taking a hike. You can stop to rest. You can choose shorter routes or cooler times of the day. It's not apples to apples. It's good to be in touch with your capabilities, to know what precautions to take and to know the warning symptoms of trouble but a reasonable amount of activity is possible for a lot of people even when it's hot.
But I think the OP has some information to work with and may choose a different part of the country depending on what's highest on the wish list.

You take snow and cold into consideration in the winter - so you should take heat into consideration in the summer.
I live in the Dallas area, and I'm planning a VERY similar roadtrip for this summer! Like, almost exactly the same, just in reverse. If you go to Texas, don't miss Austin. It's the crown jewel of Texas and is incredible for so many reasons - food, music, and the river and capitol building are gorgeous. Also, nearby Hamilton Pool is so cool! You have to make a reservation but it's worth it. Fredericksburg is a hidden gem near Austin and San Antonio as well. As for the 4th of July, Addison indeed has a fantastic fireworks show, but it's insanely crowded and there's really not much to do except go to bars (there are tons of bars there.) But if you're okay with that then by all means do it.
On the way to Texas from either Arizona or Colorado, Santa Fe NM is a splendid little town. Tons of history, beautiful scenery especially at the top of the ski basin, and great Spanish colonial architecture. Abiquiu has great desert landscapes too. I go to these places every year and take tons of pictures. I'm all about the photography too.
Good luck on your trip!!
UK traveller did this trip November 2014.
We flew into Seattle, picked up our hire car and spent 3 weeks driving down to San Diego and then across, ending up in Texas (family there).
I may be able to dig up our itinerary if it'll help. Basically we started by driving down as close to the coast as possible, heading across inland to do Sequoia (Yosemite was our preference but snow disagreed), Death Valley (motel at Lone Pine was 'interesting!'), Hoover Dam, Grand Canyon (we did the glass walkway; if we'd had time we would have gone to the 'other bit' - guidebooks will help you decide what you want, Vegas etc. We only spent a night in Vegas and chose a nice but economy Aparthotel - after we discovered that lots of the Big Hotels will do deals on late bookings. We also spent 3 nights in Los Angeles before heading down to San Diego (loved it and hubby wanted to do USS Midway tour) and then across to Texas, keeping just above the border.
We used the internet to book hotels one or two nights in advance - some were brilliant, some OK and some odd. Funnily, the odd or grotty ones are the ones we still talk about. Comfort Inns were pretty reliable - but we were in accommodation so little we didn't really care. All motels used were clean, only 1 was noisy. Motels averaged 100$ with the most expensive being around $115 - this was 2014 and pre Brexit currency exchange rates!!!
We didn't plan our route too much in advance and probably missed things. Because of timescales we couldn't 'do' everything en route and are glad that we picked up some not so famous things eg a film museum dedicated to Western Movies in Lone Pine, small but entertaining. The motel there looked like it was out of a film set, apparently deserted and complete with tumble weed and a creaking broken sign. The mountains behind it were beautiful.
Enjoy - we had a ball!
Grand Canyon (we did the glass walkway; if we'd had time we would have gone to the 'other bit'
That other "bit" is the one you should do: Grand Canyon National Park. Skywalk is at Grand Canyon WEST: closer to Vegas but not in the park and not at the deepest, most dramatic part of the canyon. It's also (sorry but I have to say it) a tourist trap with a per-person ticket fee of over $80 if you want to include a few minutes on that glass walkaway. They don't even let you take your own photos on the thing and have to pay to have one taken of you. You're not allowed to bring in your own picnic into the place.
The South Rim of Grand Canyon National Park is 1.5 - 2 hours further east but a bargain at an entry fee of $30 per carload that is good for 7 days. Take advantage of the free ranger walks/talks, and feel free to save even a little more by bringing your own munchies to enjoy at some jaw-dropping spot (although there are cafeterias and restaurants.)
Those amazing pix you've seen of the Grand Canyon? Virtually all of them were taken at the South or North Rims of the park and not G.C. West.
