At the very least place the camera on the floor of the truck as heat rises and crack the windows to vent the heat out.
Most of my best work has been out on the water and yes I have taken my D800 out with me in the kayak, as determined by conditions. I take a dry bag with me so if I have to slog through some heavy water and I stow the camera out of the elements. As long as you are competent in your boat handling skills, don't be afraid to try it. We hear all the time about "missing that one shot of lifetime".

but if you take it out and use it, do you have any problems with condensation?

Allen, my personal philosophy is I never leave my camera any place I wouldn't leave me.

My cameras spend most of their lives in the trunk of my car - sometimes in shaded areas, sometimes in the bright Florida sun. I've not had any problems as a result.

The biggest concern that I have is when the camera is on a tripod in the sun for extended periods of time: 45 minutes to an hour. The shell of the camera can become to hot to handle but functionality does not seem affected.

You might consider wrapping your gear in soft towels or blankets and putting them into an appropriately sized cooler.

Just how hot are you expecting it to be? I usually also keep my camera and other photo equipment in the trunk locked up when traveling but while actually driving or eating in a restaurant and not using it. To date, I have not had a problem with heat build up in the trunk. But my time chronology is likely different from yours. We (my wife and I ) prefer traveling really early before it get warm or the traffic builds up. So once we get to the area(s) where we plan to take photo graphs I'll have the trunk open and shut over and over and move the car likely many times. And then while heading home again the camera my experience an extended stay in the trunk.

We live in CA where the Summer heat can get up to 110 as it did last week. But I don't go out taking pictures or doing much of anything in that kind of heat. I have visited the deserts many time in Fall, Winter, and Spring and it can get warm. No problem for the camera thus far. A moving vehicle seems to stay (slightly) cooler than a parked one. A couple times when I knew it would be hot but not crazy hot, I put my camera in an empty ice chest. The insulation keeps the camera closer to "room temperature" longer. It may be safer in VA than CA but I agree, lock it in the trunk so no one can know it is there, not in the passenger area. I'm also careful about when and who I let see me open my trunk when I know I'll soon be away from the car.

We have some bold criminals in California. A professional photographer and videographer I know last Summer was at Sammy's Camera in Pasadena, CA. It seems someone noticed what was in his "work" camper (he'll actually live and work out of it on assignments) and actually followed him from Pasadena to Rancho Cucamonga to his home, some 33 miles on L.A. Freeways! Later his van was broken in to and professional camera and video and audio equipment were stolen. Luckily he had insurance so it gave him the opportunity to get some new(er) equipment. He brought a Nikon D810 as a replacement for a probably 10MP model! He is still more upset about loosing a very good and rare microphone that can not actually be replaced. Others even mourned this mic when they found out it was gone and they could no longer barrow it.

Why do you need a camera on a fishing / camping trip? Use a SmartPhone for the big one that got away. And the bear that ate your food. Kidding a bit now, but get my point?

I would leave my camera at home.
Sorry I thought you were leaving the camera in the car for 4 days, my bad

I do ball games for the grandkids. I have a wheeled cooler in the back seat to store my gear. A good seat in between innings, & I nice stand to get over a 6' fence.

My rule has always been that the driver's first job is to cool off the car - open windows, start A/C, etc. Normally I remove camera from cooler only once that process is well underway.

I have a medium size cooler in the trunk. Makes it both out of sight and protected from excessive heat. Also use it for my laptop.

My camera survived Death Valley! :-D on a motorcycle...
