Now that you've had this SPAL fan running for a year, and it's summer again, what do you think overall? Major difference for the A/C or marginal? Would you do anything different?

The fan works great. I notice it most when the engine is heat soaked and driving under 40 mph. At this point I am happy with the install. I wouldn't advise having to do anything differently.

Thank you. Does it maintain vent temps at low speeds as well as the ram air of freeway speeds?

Yes, but I have not used a thermometer to measure the exact temps. If I feel my AC lagging I turn the aux fan on and the temps definitely drop. My rig's AC has always struggled at low speeds. Regardless of fan clutch mods, radiator replacements, coolant types, etcetera. This mod seems to have fixed the problem. It has zero effect on engine temps. But, you probably already know that

Great, that's what I was hoping. I'll have a parallel flow condenser in soon and will plan on incorporating the SPAL fan to push it over the edge! My clutch fan mod keeps the engine very cool but doesn't do squat for the A/C, especially in town and on the trail.Yes, but I have not used a thermometer to measure the exact temps.

So I just installed a pusher on a relay and rocker switch on the dash… it works well but on my first drive with it actually raised my engine temp was higher with it on than with it off.. I ran it from the start and my temp increased to 192.. I turned it off and it dropped it 185 which is what it normally runs at unless it’s very hot.

You are not supposed to use while driving at high speed (think freeway). It blocks the radiator. It simply does not spin fast enough.
You should only use it at very low speeds (as in off-roading or in stop and go traffic situations) as there is not much air going through the radiator.
