Things we are very happy we did (as a result of going over this thread in great detail and seeing them at Expo West):
1. Barn doors (halves) and having the first door opening on the passenger side instead of drivers.
2. Hatches on both sides. I passed on several used OVRNLD setups because they didn't have hatches and now that we have them I am so glad we do.
3. Rear Slider window to cab. So nice to be able to open and get airflow during rain. Our dog can go back and forth into the truck through it as well, and we can see out the front to see if someone is pulling into our camp site.
4. No windows on the rest of the frame portion of the camper.
5. Extra bedding height. We did +2 inches.
6. Maxxfan. I like it. I wish we had the remote control one but the exhaust only has worked great.
7. Clear vinyl windows are a no brainer.
Things I would have added are:
1. Solar gland (this was a pain to install later).
2. I'd have gotten anodized on the sides (silver or white). I like our bare aluminum but it does scratch easily.
Just my 2 cents,
1. Flip up rear door, I have a swing-out tire carrier, barn doors wouldn't have been beneficial to me.
2. Hatches on both sides? I am happy with one, but two would have been okay.
3. Rear slider window to cab? I had one on my last camper, and I rarely used it. So I couldn't justify the cost, and I have no dogs.
4. I went with the white painted siding and I like it.
5. Clear vinyl windows are nice.
6. Fabric headliner, I feel this should be standard on all models.
7. Awning mounts for batwing awning and shower awning.
Things I would have added or did add:
1. Extra bedding height, while I make it work, I wished I had gone with it.
2. A rear window on the flip up rear door, for viewing purposes.
3. Bolt my camper to the bed, will do later.
4. Gas struts, I had to purchase and installed them after the fact, and saved $150.
5. Daisy chain straps and extra lighting, I installed my own and saved $500.
6. Positive pressure vent, installed my own and saved $75.
7. Maxxfan Deluxe, I installed my own and saved $200.
8. Folding counter, installed my own 16" x 72" and saved $380.
I love this camper, and it will always be an evolving project.
