Been hauling a V nose trailer since 2009. In ours, the kitchen is in the nose. This gives more counter space and a more spacious feel. The propane tanks are in a compartment on the near side of the nose and are easy to access. The battery compartment is on the off side behind the water heater. As to the hitch, we use a Reese Pro series with square bars that seat on friction brackets on the tongue. This acts as sway control as well due to the brake pad material on the brackets.
As to the towing, I have noticed less side buffeting when being passed on two lane roads when compared to a standard trailer. Gas consumption doesn't seem to be much different though.
As to the comment about large trucks not using v-fronts, I can remember hauling trailers back in the day with round or slanted fronts. They stopped using them when palletized loads became more common in shipping.
JMHO YMMV
