To answer the question you asked, I suggest the lightest gray that you can get, which will help you keep it cool in the heat with your new air-conditioner (another of your threads). It is easier to heat it in the cold rather than cool it in the heat.Alright, we are pulling the trigger on a color change.
I have the time to do it before our next big trip, so now is the chance...
The entire thing will be coated using Monstaliner.
But I need your help with colors, er... grays...
Bright white to match the truck is just entirely too much white.
So Im going the direction of gray.
First photo is how it sits right now, with an off-white finish.
Then light, medium, and dark grays...
Please give me some feedback.
I suggest you paint it white to really help you keep it cool, and to avoid being hard to see in fog and heavy rain (which gray tends to do). Yes, I read that you think it would be too much with your white truck, but, I urge you to reconsider!
