Don , that was an early sketch... I've now learned simpler is better ... All that wiring /plumbing is just more trouble than it's worth .. The more complexities , the more maintenance/trouble /expense ... Initially , I was looking to replicate a "home" environment ... but as it turns out , it's just overkill for camping .... and a lot of dead weight to haul around...
After selling my TD, The wife insisted on buying a travel trailer (Jayco FS 197) which is Cute as a bug inside , but waaaaaay more than we need , and turns out to be a maintenance nightmare ... the trailer falling apart faster than I can pay for it ... Grrrrrrr!!!!!! (poor design and construction) Buying that was a BIG Mistake ...
Since hindsight is always 100% accurate , I've learned now what I need is a well designed and constructed trailer with the simplest of accessories, that can be fixed/replaced easily and at little cost ... Seems like "RV" appliances are 10 times the cost , and dubious quality ... and the outside maintenance is designed for frequent dealer repairs ($$$$) ... It's a "game" designed for the rich to pay and pay ... keeping the dealers flush with cash ...
Now I've been going around talking to every cargo trailer owner I see, and all , whether a landscaping contractor , plumber , tradesman, have reported ZERO problems ... Even leaving them outside all the time ...
Now being an old retired guy , this is what I need , not some money pit "RV" ... A homey interior would be nice , but Now I've learned (the hard way) that all I need are the essentials items for basic comfort ... Good bed, AC, Igloo , a reading light , and lots of pillows ... Appliances are pared down to a simple (cheap) electric hotplate , coffee maker , and possibly a cheap microwave... Hibachi for outside cooking ... And the requisite porta potty too ... A cheap dorm refrigerator < 100USD does the same thing as an RV 3way reefer, and at one fifth the cost , and no worries about clogged vents ,leaking ammonia etc. ....
I should have known better after all the reading I've done here for years , but just had a serious case of the "Dumb arse"

.... Better now ... especially since discovering cargo trailers ... Keeping it simple , but comfortable ... Best of all , with a cargo conversion , I'll be able to have all the comforts I need for Half the weight of my Manufactured TT... easier for the old 6 cyl. Silverado to tow ... and about a third of the price , and best of all , NO bimonthly trips to the dealer for ridiculously expensive repairs ... Funny how an RV dealer charges more for labor than my Doctor ...
Keeping it simple , and cheap ... that's Me !!!!
Still looking around for a used CT ... problem is , they work so well , nobody wants to sell them ... Travel trailers are for sale everywhere... most folks taking a big bite when they sell, them too... or try to sell them ... I think people are getting wise to the RV game ...

Once burned ....
Sorry for all this verbal rambling , it's just very exciting to find something that really works well , and doesn't cost as much as a truck ...
