Totally, I've never been around such a group of overly paranoid vehicle owners who want their rigs to last forever and look good while doing it ( sometimes, myself included lol ) The entire 'overland' market of goods out there isn't helping, trying to tempt us with expensive gearFunny how the Jeep guys and other communities find cheaper ways to do things compared to us Land Cruiser guys.
Jeep guys out on the trails, they have fun, they beat s*** up, break it, build it up again, and repeat. I'm used to run a inline 6 jeep when I was younger, I think the XJ? for several years. So much fun, I would just throw s*** on the roof, strap it down, and beat the piss out of it.
So to the OP's question, you'll get a mixed bag of opinions here. Just buy and build your truck based on your needs. If you find yourself in sudden storms and other conditions, that for some reason you then are going to stand outside in, then maybe a quick awning is what you need. Or if you're so loaded you have no space left to spare, maybe the awning mounted up there is a good idea.
But if your just cruising around , want some shade at camp, have a few minutes to spare, and you know how to run a guy line, then just get a tarp, pop up shelter, slumberjack tarp, etc. Everyones needs will be different, so buy accordingly.. I am biased but I can assure you the slumberjack will provide you with the most possible shelter and coverage on the sides .
Here is a forum with some pics, take note of how many of these cast virtually no shade and then oh s***, the sun moves in the sky so now what? Sure still some protection from rain and all that but IDK just not for me.
Awnings, let's see them
