The link you posted is for a 198RD, which is what I have. I checked out this new 195RB and here are my initial thoughts:
-that's a pretty long trailer for a single axle, and sway would certainly be something to worry about. it probably wouldn't tow that nicely.
-this line of trailers is designed to keep GVWR below 3500lbs so that salesmen can tell you they are minivan & SUV towable. All this means is that the larger the trailer in this line, the less payload you have for gear, etc.
-by the time you add in your battery weight, any accessories, and heaven forbid you travel with any fresh water in the tank, you will have next to no payload left for your essentials.
-the only benefit i see to this floorplan is because the bathroom is in the rear, your hitch weight is less and won't kill as much of your tow vehicle's payload.
Conclusion: if you want a trailer 19+ feet, step up to the JayFlight Swift line and make sure you have enough truck to deal with it. if not, consider a shorter, lighter trailer, or a pop-up.
