Often in these type threads a person will ask if something is suitable and will pretty much state honestly that they have $800 - $1000 to spend. ...
Good point, Don. In my first post, I specifically asked for "the best" - with cost a secondary question. I am retired and "on a fixed income" so I'll have to factor in cost, but I want this bus to be my home for as many years as I have the health to do it -- I'm not going to waste money, but I don't mind a wise investment -- by "wise" I mean something that works well now and is reliable over the years to come. So, I don't mind that people have described expensive units. I'm going to take their descriptions of their experiences and opinions and put them into the many-factor mix.
To have a unit that will take me until I'm 80, it would need to last 14 years and be suitable for the technology of 2028. I think that means that I'll need to go with "what they now call 'pure sine wave but really isn't'" for it's technical capabilities. I got a bit stung on the Outback purchase -- I didn't do my figures right and bought too small a unit and misunderstood it's listed claim for "load-shifting" versus "load-sharing". I really appreciate that people have described the load-sharing abilities of the equipment that they've had experience with. That's been the help I've needed.
I'm not sure that I'd have replaced the Outback (although the lack of true-load-sharing would have been a burr under my saddle for as long as I had it) for what I've got planned but an engine change makes a move to a 24V house system pretty much necessary. And 24V on the house system will be better for higher loads of systems like the air conditioning system I have planned for the future.
I have sort of assumed that buying used unit off EBay is a little risky for complex electrical equipment that's supposed to last 14 or 15 years, esp. since I have not had a lot of experience installing, diagnosing, or repairing electrical or electronic equipment. I think I'll have a good discussion with myself, but it seems that that's a pretty good assumption *for what I need* (not saying that it is the way to go for anyone else).
I appreciate your input on this thread and the fact that you've taken the time and energy to help - a lot of what you've talked about is "going back to the basics" and that's been especially helpful. Thanks, and Good bussin' to you!
