It looks like the previous owners didn't have the TT for very long to add their personal touches, maybe the layout, size, or whatever did not suit them and knew they were going to sell rig early on.
I've seen too many used RVs in the past where owners went way overboard on making changes, at times losing the original appeal that made them purchase the RV in the first place, not always good for resale.
We love making mods to the RVs we have owned, mostly to improve functionality of the rig. We replaced mattresses, added powered vent fans/covers, installed inverters and boosted charging and battery reserves.
