Pretty uneventful 100 mile trip, the colorado handled the 2015 Jayco 23RB just fine. I was disappointed in the 10.3 mpg, but I think it was all mainly uphill and the dic showed an increase in mpg the further I went, also rpm's dropped.
I think the computer was relearning how to shift with all that weight in tow/haul mode, hope so anyhow.
My first jayco. Someone is supposed to come and look at my old terry resort tonight, hopefully they buy it.
