Lots of good suggestions here. We got the combo micro / convection oven. We don’t use either much, but there are times we really want them. We do not have an inverter, so need shore power for that. We have a generator, but it gets used less than the oven just to charge batteries if it’s been both cloudy and cold for several days.
Manual awning is much more functional for us, but does make sliding windows more useful. I’ve thought about changing the DS dinette and the kitchen window to awning style since they seem to generate less condensate drip. We have the split rear awning window. I prefer the bath slider as I can pop the screen and use my waste water hose for a good black tank flush.
We too use the electric water heater anytime we have hookups.
A/C is the Coleman. On low it has almost the same noise level and cooling output as the Houghton. Low is all we ever need. By using low, you avoid much of the short cycling issue. We also have the heat strip. We use it anytime we have hookups into the mid teens F and it keeps us warm. The Coleman made the A/C one less thing I had to install.
We also had ETI install a slightly wider sink and like that change as well.
We have the double step and lift. I prefer the trailer higher, but that has pro’s and cons.
We like the warmth of wood, but a light bright interior, so we went maple with white formica.
Solar is a must to me, but if you always plug in you don’t need it.
Everyone has preferences. Only you can decide what’s right for you. I’m not sure if CPAHarley has it figured out yet.
