I have the lighter GearSpace 20 with landing wheels and found on my former 2005 Pleasure-way Plateau that putting more than 150 lbs. in it made the front end feel a little bit squirrelly. On our first trip out I had it full and ended up taking stuff out and putting back in the van. I haven't used it yet with my Great West Van. We bought it to haul our two inflatable kayaks (70 lbs total) which tended to smell if stored under the sofa and bed after use on an algae pond. You'll have to load it up and see what is comfortable to you.
