Sounds like you got a great trailer and are on the way to making it even better, congratulations!
7x14 is definitely a REALLY good sweet spot in terms of size. I miss the agility of a smaller trailer with the 8.5x20 trailer for sure. All the time when I was trailer shopping I constantly kept asking myself what I value more: Being comfy when stopped or being comfy when towing. The amenities of the bigger trailer are nice but I've found I really have to change and adapt my driving style when not on the highway compared to a smaller setup.
Also gotta say I love L-track, that's the way to go. Maybe, in the grand scheme of things, it isn't "better" but it feels slicker and you can really dial in locations of stuff due to the smaller footprint.
