As to how I like the trailer, I think it is great. The only problem I have had with it is at almost every campground someone wants to check it out! About the only thing I would do different is I'd replace the rear dinette with a bed. I have only set it up once in 97 days, and that was just to try it. I travel by myself & when friends visited the three of us managed to eat at the front table without problems. Actually, most of the time we ate outdoors. I currently sleep on the rear dinette set up as a bed, complete with a 2" topper. By the way, if that is the way you are going to go, ask Reace to move the AC receptacle on the face of the sink as high as possible.
The best option for me has been the front storage unit. It is a bit tight to open & close with the dual propane tank cover, but I'll be able to fix that when I get back to Oswego. I still haven't decided if the 5 cu ft fridge was the right decision. I don't keep it full, so maybe I could have gotten away with the standard fridge & had space for a microwave. Then again, I haven't missed a microwave.
As to other options, I ordered the trailer with almost all available including the 95 Watt Solar Panel. The panel keeps up with my heavy laptop, router, and other electronics fine as long as there is sun. When I was in Apgar parked in the shade for 3 days it didn't ever get back to 100%, but when parked out from under trees, even on cloudy days it keeps up.
In addition to the back up camera on the 17B, the other modification I asked Reese to add was a "Wilson Electronics 801212 Cell Phone Signal Booster Kit". It includes an external antenna, a 3 watt amplifier and an internal antenna. Rather than use the external antenna that came with the kit I used a "Wilson Electronics Dual Band 21.5 inc RV,Trucker Cellular Antenna Kit with Mount" which has a bit more gain. The external antenna is on the rear driver's side while the internal antenna is mounted center front (on the face of the shelf). This provides an increased cell signal in the area within 4' or so of the internal antenna. I added a WiFi Ranger router that lets you choose between the campground WiFi, a USB cell modem or a Ethernet connection for inputs & provides a local WiFi signal that is strong enough to cover a 100" radius around the trailer. If you have multiple devices that are WiFi enabled, you only need to change the router connection; your devices all stay connected to your local WiFi signal. Another advantage is the router's WiFi signal is strong enough that it covers my iPhone while driving. I like to use the Public Radio App to listen to my hometown NPR station (WRVO). If I don't have AT&T coverage I often do have Verizon, the service that the cell modem uses.
Because I update my travel, photography & RV website often, those modifications work well. You probably don't need them if you are not an internet "geek".
I also added a Progressive 30 amp Power Monitor. There is another thread describing it - Power Conditioner
. I also switched out the "Quick Links" used to connect the safety chains for heavy duty snap hooks, making it much easier to hook & unhook.
That's about all I've done so far. I have a 15' LED strip that I'm going to add just below the awning to provide some interesting night lighting, and I will probably add a small inverter to provide 120V when not hooked up to AC, but that's all I have planned right now.
If you have a specific question, I'd be glad to try to answer it!
