I think I'd also just leave as is. I just did cosmetic things and the lift since my tow vehicle was so tall. I do enjoy the lift although it makes it a big step up into the trailer, it could be solved if I bought a new step to put on it, but for now I'm good with my little portable step stool that was multipurpose

I also took the shower curtain out of bath since if I need a shower I'd likely just use the outside one anyhow. Do you feel a lot of pull with the liberty? I had a traverse and mine did have a lot of pull and tug feelings, but now it's like it's not even back there. I also don't have electric brakes with my model and not sure about yours. I think if I did anything else to mine it would be a cover for the gas stove to allow more counter space. I had a serving tray over it last year, but I used it for something else and didn't have it in the camper this last weekend. I have moved my stuff around a little and bought a couple items for most of my storage since I cook outside 100% of the time, it just made it easier.
Here is my stool- holds bug spray and cleaners

and this now holds my plates, cups, bowls (paper and plasticware), storage containers, utensils, can openers, measuring cups, anything I'd want to have to serve a meal or help prepare. I figured if I sold my camper, I'd still be able to tent camp until I found another camper and the time

Meanwhile I use my drawers for extra batteries, foil and cling wraps, baggies and such. I use my closet for extra TP, Paper towels, camp forks, lights, trash can etc. In my bath when not using I keep my broom and my laundry line (which came in so handy!)

I think after just a year I have how I like it down and the items I actually use vs just to have. I recently sold a little from my camper stash that others said "you need this" after being out and about, I didn't really use so why take......
