Yes, it likely will take several different ideas and combine for the final plan!
Thinking of alternates, keeping in mind that we want to stay light and also storage.
I did a search of "bed frame in a box" to see what might show!
I've been hanging around too many college folks that want it cheap and portable!
Since wood is so much higher than I like to pay, combined with not especially wanting to start from scratch, I thought this might be a way to go as an alternate that has very little finish work of any type.
Basic box but with pre built storage. Not too expensive when compared to buying wood, etc. and finish stuff?
Maybe screwed to blocks on the floor to make it stable?

Lots of the knockdown furniture is good for RV as some is the lightweight we want.
Plenty of options to mess with the planning !
