Why would you want to get away from propane? That is the single system past water that allows for independence. No upside to it as stove, oven, water heater, furnace and refrigerator all run on it. It is the heart of an RV, literally.
And taxing the electrical system is NOT a good idea, IMO. These things are not built like houses when it comes to code. At the least I would replace circuit breakers if not converting to 50A.
The main problem is with the trailer design & construction of that type. The roof fails almost no matter what and moisture delaminates the walls. Just a matter of time. Lucky that you are in a dry climate as this is less apparent. It's happening, and don't believe others that it is not, or that repairs or coatings will prevent it. They do not. They only decrease the rate of disintegration.
What makes one like mine more desirable is that the roof pretty much won't wear out. Slide outs are the same problem as the roof as a hole in the side begins the warping of the structure. I would avoid them like the plague.
And a complete package of awnings makes it a bit more sun-friendly. Maxx Fans are the best recommendation for roof vent replacement, and consider a patio awning with screen room.
Reflectetix works well for me. Windows and interior side of roof vents. Buy the tall roll and plenty of the tape.
I'd spend more time on denying entrance to rats and mice over other concerns. Pack rats are among the worst. Mice need quarter inch openings and rats 1/2 inch. Bronze or stainless steel wool anywhere an opening can be found on underside. Hardware cloth epoxied in place, etc. Be sure to replace grey and black tank vent gaskets pronto.
I like having a travel trailer as my home, but maintenance per square foot is far higher than a fixed abode. Same for utilities. Which is why propane power is important. One can spend quite a lot of time off grid in non Texas summer weather. I find a two week goal more "practical" as it is in line with mobility. This is where solar electric starts to make sense. With a big enough system and inverter generator one could even run A/C to a degree. But I couldn't say I'd want to spend that money on that 5er of yours as it is closer to being timed out.
Look forward to more. Plenty of great threads for you on

If you really want to "save" then get a 2003-early 2004 CTD truck like mine. A really sweet example for sale in AZ right now. 2WD, manual and looks like new at 100k miles. Already has right hitch for yours. Note my fuel costs in signature at $2.70/gl.
