Don't forget, an RV is considerably larger than a car and the temperatures inside won't even come close to the high temps found inside of a hot car.
Actually just as hot, it just takes a bit longer to get there due to the larger air volume.
Not really, for a few reasons. First, by heating up more slowly, it will not get as hot before nightfall comes and it starts cooling down again. (Unless one is at an extreme latitude, night will come periodically.)
Second, a car generally has a lot more exposed glass in relation to its size, and so acts more like a greenhouse. This means more heat gain inside, and a higher ultimate temperature when everything is in equilibrium.
Third, the RV is much better insulated than a car, and so there is less heat gain from the outside walls and roof. This would be especially true for a light colored RV (or at least light colored roof) and a dark colored car.
For that matter, cars do vary quite a bit in how hot they get, too, depending on their design and color. My Honda Fit heats up in the sun a whole lot more than previous cars did, enough so that I bought a windshield sun shade very soon after getting the car, even though I had never particularly needed one previously living in Vermont.
