Not too keen on a/c in confined spaces.

How does your unit get ample fresh air and expel the used?

Same with friges - air circulation critical. i have an Engel freezer/cooler
that I have just put a new compressor in ready for resale (new frig has
enough freezer room for just the two of us) and the performance
difference in the van under the table and when outside the van
under the annexe is spectacular.

26 deg to - 18 under table 1 ¾ hours
26 deg t0 - 18 under annexe - 1 10min.

Not too scientific a test but gives a good indication. wanted figures for adv.
