I guess it's according to how much and what type of camping you are going to do, if your going to use it 3-5 times a year and only in campgrounds then it's a toss up, but if your planning on keeping it for some extended trips and maybe some off the beaten path trips on curvy hilly roads and such for me there would be no problem making up my mind....the DRW will be much more stable.
I have an 03 lance 1071/slide the tag says 3,600 dry, I first had it on a SRW but quickly realized I really did need a DRW with some suspension mods.
I'm not one of the guys that says, " heck I don't even know it's back there.
