Custom interior on factory sleeper

Has anyone had the interior of their factory 63 or 70 sleeper customized? What did you have done? By who? How much? DIY? Pics?
I personally love pete stand ups, but their interior lay out is 1980s tech and have wasted space. The newer models are pretty, but chinsy. So I'd like to kinda redesign an interior with old quality and new layout and electronics...ie USB ports, better shelving, fridge, practical use of overhead space, maybe a sink. I also loved the fold up bed with the table and bench seats pete used to have on the first 70" models with the ##### door, but I'd rather it be a twin size instead of a full. Anyway, suggestions, ideas, and any experience are appreciated

 

I think the 300 was great... back in 1980. Lol. It's just time to update. I want the quality of 80s and 90s but the creature features of today. I'm not sure the cost of having legacy redo my sleeper. That's one I had not thought about. But doing it myself seems more likely for me

 

I'm not just after USB. I want the sleeper to be more ergonomic and better functioning. A little more comfort and better use of space. I don't need two hang up costs. One would suffice just fine. Maybe 2 or 3 drawers. Decent refrigerator. Entertainment/TV/PS4/ laptop area. Pull out or fold out desk top. A little shelf by my pillow area for my phone, glasses, misc crap I keep with me all the time. I'd also like I hidden area... like secret compartment about 25"x15"x3" that I can access easily if I need to. Probably going to have to build this myself. Lol but I'm looking for any insight, suggestions, or pics
