1989 Toyota Dolphin A/C

[Rich8803]

I'm looking at buying a 1989 Toyota Dolphin.  It does not have a generator.  Is it correct while driving the only A/C will be the dash?  Can that possibly be sufficient to be comfortable in the RV on summer days?

yep and on hot summer days IF the engine driven system is working properly will cool the cockpit - the back should get a little cool.

If the engine driven ac is weak --- ouch!   I have seen people put a sheet behind the cockpit in an attempt to keep the cool air in the front.

When evaluating the ac - put a thermometer in the center output vent - if you are getting 40 degrees that is good.  50 degrees ....  well it should be ok.   

Some people add a generator to the rear bumper and run it while driving so they can run cabin AC

It all depends on what the outside temp is as to how much the dash AC will cool the house  I do a lot of desert driving and when I had my toy, it got a plastic shower curtain between the cab and house. At about 100 deg I would start the generator and run the roof AC to cool things down. 

FWIW last summer we took the new (to us) Winne to LV it was 116 degrees, it took the dash AC and running the generator with  both roof airs to maintain 80 degrees inside.
