This is a comparison of many of features we care about in the Brinkley Model Z 3515 and the Keystone Cougar 360MBI. The weight calculations assume that we can drop 200 pounds of added shelving weight added by modifications to our current RV. The weight excludes the 500 to 600 lbs of fresh or waste water that we do not carry between campgrounds. The spare cargo weight capacity is expected to be at least this.
The Cougar 360MBI has a layout that we know works for us, except for the office cooling. It is also about 2,000 lbs lighter and might (just barely) work with our current truck. The unloaded hitch weight is only 17.5%, which is a bit low. The Model Z 3515 is only 18.5%, which is also a bit low.
We have some things that we did not think of when looking at the Cougar 360MBI, so we need to go back and check for those.
