I am glad to have the rear air too. The front only isn't be enough on warmer days (90deg). Any other time it works great.
I haven't been able to get the heat very hot yet. I may have to change my thermostat to run a bit hotter. For instance, in the mornings where the window fogs, I tried the defrost and while it works for to clear the window, no way is it hot enough to heat the cab. Water temp is running 170ish even during the day. These are days where its still warm enough to ride with windows down. At worst it gets down to freezing here and it'll never make it on those (couple
) days.
I guess blocking rad works too. Any other suggestions?
