we are slowly moving (once the funds allow) to do a similar thing to you...
we have a cheap, soft floor camper but would like to move to something that is more suitable for weekend/long weekend trips...
we find the soft floor is OK if you are going to be in the same place for an
absolute minimum two nights, but not suitable for quick overnight trips, or a quick sleep stop when doing a longer trip. we have many places around our area that would be great for overnight camps, but the thought of setting up the soft floor for one night is not appealing.
we have our hearts (at this stage) set on a modcon quattro (link below) as we have two boys and being able to just open out the main tent and just go to bed (two single beds with bedding already setup) is very appealing for us.
http://modcon.com.au/campers?camper=5it comes with a touring awning for the quick one night stop, or a proper annex for long stays...
some of the cub campers are also appealing as well...
having said that, i agree with what others have said about being
as organised as you can be, and in that spirit, we are hopefully going on our first trip this weekend after purchasing a drifta kitchen (with return) and storage box (after just having the kitchen on the tailgate).
already we can see how this design will make setup and packup more efficient.
we also have purchased a 3x3 aluminium frame gazebo for quick extra shade (fits under the camper trailer cover), rather than adding extra annex tops, sides and poles...
