nope there still darn good believe it or not and with that 24V and a modded blower
it will run you out on LOW

all that day I wore under armour cold gear and a T shirt with the window down and the heater on low it was great and thats how I roll 90% of the time

I wish I could find the time to fix the gap between the bed and the cam i need to cut the frame 3 3/8 inch to make it look stock and thats ALOT of work for 3in IMO so I am looking at other options
