You shouldn't have to worry too much about egt's with that set-up. I just like to look at stats and numbers regardless if I'm towing or not; for my set-up with the scamp I wouldn't go without a scanguage, very helpful.wow, thanks for the great photos and info. We are heading out Oct 2014 for 10 months, throughout the US and Canada. pulling a 2013 Prolite Suite, similar but only 500 lbs dry weight. wondered about putting an Egt in, but only 500 lbs, two adults in the car? thoughts?
