I think it depends on your idea of handling.
I want mine to handle as good if not better than stock. (mine is 4 inch lift, long arm rear, superflex front and adjustable king shocks). At the moment I can easily take the ute in an out of understeer (dirt or bitumen), its very controllable with fine throttle adjustment even though I have no ability to make adjustment to increase/decrease understeer, Its just what mr nissan gave me and that is my limiting factor and I can deal with it as I am hitting a corner pretty dam fast when it decides to let go.
Oversteer is good to a point where if you get it out too far the lack of sway bar (just need extended links and drill and tap superflex arms and they will be reinstalled) come into play when you correct, the body flops around and unsettles it wiping off whatever speed I had or directing me to the closest tree then the closest toilet lmao
If I just put it into oversteer when exiting a corner as fast as possible as opposed to 'drifting' if you could call it that lol, again its controllable with fine throttle adjustment the rear just squats down and sits there and even though I have broken traction its still putting power to the ground and still accelerating at a decent rate (as much as my boosted diesel will give me).
with a few more add ons and adjustment I think I will accomplish what I set out to do handling wise
As for the tray I have a thread in the DIY section. Its just a google sketchup drawing atm I havent done anything more than that.
I have a 130L tank under the tray which I need to get modified so I can sit it lower and it wont foul on the drive shaft. I am going to build the tray as low as possible. This is where comprimise really starts to kick in. Its probably going to be heavy, and space is going to be taken up by wheel arches and I need to make provisions for shock mounts. I would like to section the rest of the tray for storage and have it so when it is enclosed I have a nice level area to sleep on, then most likely a cage and canvas canopy. Still all on paper at the moment it will no doubt change in time.

This is where it sits in the flex department (although it looks stupid on the 31's but its the most recent shot lmao)
