WOW! One could almost get whiplash from thinking of the differences in those!
But much of it is going to be personal choice combined with what you plan to do with the RV???
So I might throw in some of my personal thoughts but do consider them to apply to me and maybe not to you!!
I tend to like newer/smaller but hate some of the newer issues they have added for me to try to sort out and keep working. How do you feel about adding tech if it also adds to the failures?
Of those two, We would not like the Murphy bed as when we want to lay down, we certainly do not want to be making the bed! They seem to be lots of reports of problems with the movement but mostly it is just not for us as we want a full time bed.
And the personal choice thing comes in again on the engine as we have not had anything but gas . I watch my brother and we are glad to avoid diesel!
A site to do lots of detail looking at where they may have built in some problems is this online parts catalog that lets you do lots of looking through the walls at things like where the tanks are put and gives details on volumes, etc.
Winnebago does do a great job of given us lots of info online.
Under the owners tab and drill down into lots of specifics on drawings and diagrams as well as the sales booklets?
One of the big things about RV is that there is a super wide range to fit our personal tastes.
But it may take forever to find out and it does keep changing over the years, so there may not be a firm answer!
