From what i heard .. ARB only offers one size fridge now (42qt). So you'll have to go with Engle if you want a smaller fridge. Dont know this is a fact. You should call.
Have you considered selling the 43qt and stepping up to a 60qt? Not sure of your needs, but if you could get by with the 60qt, it would sure take up a lot less room (not to mention battery drain) then two fridges. Yet another option would be to consider the Two-Zone addition for your 43qt, someone here on mud is dealing them as well.
I agree-this would be a great set up for longer trips. Imagine ice cream served up on day 5! If you have room, it would be great to have 2 fridges. One of our friends has a 17 qt Engle which would be an ideal second fridge, and it's small enough to tuck in anywhere.
OK I guess I will post on the vendor site as to wh will give me the best deal. The best deal will earn a sticker on my 60 at the black Hills cruiser Classic.
Thanks for the feedback. I am going to go with the twozone for my 45 and am looking at the Engle 15. I think the 15 is a good size for day trips especially in my FJ40.
4x4 Connection is currently having a 10% off sale (until June 30th) and they sell ARB and Engel both. ARB comes to $662, Engel (43qt) $627. Shipping to Iowa is $43.
