PK,
For our use, the extra vent and fan was a must. I don't know if they offer a vent-only. The vent/fan combo may be the only option but that is what we wanted in the second spot anyway. We use the cabover vent every night and the fan almost as often. Most RVers and Campers tend to keep a window and/or roof vent cracked for ventilation at night. Having the extra vent over the cab lets you easily adjust it during the night, if needed, rather than get out of bed to adjust the vent in the main living space. But even more importantly, I find that there are a lot of nights where I turn on the fan, blowing in, to cool off when I first go to bed and my wife is getting ready. I'm always warmer than her so a nice 10 minutes of laying there with cool outside air blowing is great while she gets ready for bed.
I've seen slightly different placements of the extra cabover vent/fan. I think OEV typically place it in the front center, nowadays, which then offsets the LED light to one side. When we ordered our CAMP-X, we requested the cab-over light be centered and the fan offset to the drivers side, which they did. This puts the vent more over our heads/torso as we sleep east/west with heads on the drivers side. Offsetting the vent to the side gives more direct exhalation venting at night and more direct fan breeze or suction when using the fan. Not sure if the offset location is still an option or they only center them nowadays.
Lots of varying opinions on awnings and racks so take the following input for what it is; An opinion. And an opinion based on what works for us specifically. Everyone has different needs and likes different looks. I'll mix in a few more fact/consideration as well.
We are not fans of awnings. They add cost but more importantly, they add a fair bit of weight. For those using fullsize pickups rather than Heavy Duty pickups, they may already be at or over max payload with the camper, water tank full, batteries, propane, gear, passenger and pets, hitch mounted rack and cargo or trailer tongue weight all added up.. Awnings often shade the wrong area depending how you park plus, awnings that fit our sized campers are fairly narrow and so throughout the day the sun moves and the shadow cast by the awning moves often making the shade unusable. You can't use them in the wind or if you park too close to trees or poles.
We typically find our sitting shade under a tree or in our small 6' x 6' Clam hub-sided screen house. I carry a white tarp and occasionally put that up to block intense sun on the camper and equipment. Tarp weighs 1 pound rather than 50+ pounds of an awning. Since the primary reason I ever deploy the shade tarp is to shade the camper itself, it can run at a steep angle and shade the camper much better than an awning could. Might set a bicycle or other gear under their, too, to keep sun and eyes off that if we are camping remote but are close enough to be seen from trails. Another point to consider is that camper awnings are attached to the main body of the camper and not the rooftop and so will not shade the softsides when popped up. And again, the sun may be shining from a different angle than the awning covers unless you intentionally park the rig with the awning side of the camper facing south which may directly work against where you want the window or door to face or the slant of the terrain. The white tarp allows me to clip to the L-Track at the very top of the camper so it shades the softside. And I can set up the tarp on either side of the camper, or fold it in half and set up on the rear of the camper, or move it throughout the day rather than having to park the entire rig so the fixed awning is in the right spot to block the sun. Even this tarp shading we don't bother with very often so for us, it makes sense to have a $10, 1 pound tarp along for those occasional instances rather than a 50+ pound and $$$ awning.
The various racks are useful if your using them. We wouldn't so no reason for us to have them. On gravel roads and wet or slushy highways, the vortex pulls all that road grime or dust that is kicked up by the wheels and coats the rear of the camper so a rack and anything affixed to it would get equally grimy. I don't know how far the molle rack sits off the camper, but could be tricky getting a wash mitt or sponge under there to clean. Basically, one must consider that anything hung on there will be very exposed to dust, road spray, salt in some areas in winter, prying eyes and sticky fingers (theft). Several of these are not things I worry about, but mentioning as they may be considerations for some users.
Moving on to aesthetics...I'm hesitant to give my opinion for a couple reasons. Looks are really in the eye of the beholder and because other peoples opinions on looks shouldn't influence yours. Get what resonates with you!
I'm very much a form-follows-function personality and for that reason alone, the looks of the molle racks and empty awning brackets, that are now standard, do not resonate with me. That is 100% only because we'd use neither.
The built-in awning brackets stick out and if we never use them, why have them? Even if very minor impact, they may catch more wind at highway speeds and may catch more tree limbs and brush on tight trails. Though there are many features, that have been introduced on newer campers, that we like, the lack of awning brackets is one thing I very much appreciate on ours. Would be nice if that was a free option (choose with or without brackets) but I get that it is much more convenient for OEV to build them all the same. Not not a big deal in the big picture.
If the molle rack were white to match the extruded aluminum camper frame rather than black, to my eye that would blend in more, but then, they are there to be used so if one has equipment and storage solutions covering most of the rack, that would break up, and make less conspicuous, the black large area. Keep in mind the rear door's swing-direction has been changed and so is now hinged on, and swings towards, the drivers side (you may want to confirm that). If so and one is getting a molle rack on only one side, this may impact which side you choose. The drivers side rack is smaller, but if you are hanging items that stick out, it may interfere with the door being held open or, if the hung items are hard and sharp edged, mark up the back of the door.
It tried to mainly put factual considerations out there but some opinions are mixed throughout. Sift as you see fit! Ha.
