The length of the 27 foot Nexus Viper is actually 28.5 feet. Like yourself, I have read some serious negative reviews on the Nexus line.
Just down the street from the Nexus factory is the Phoenix Cruiser factory. PCs are scaled-down by design to make them more friendly to drive and maneuver.
CLICK HERE to watch a You Tube video that compares a Phoenix Cruiser to a similar floor plan of what they refer to as Brand-X. I recognized Brand-X as a Nexus Viper. A lot is nit-picky trivial stuff, but there are some serious matters too.
