Yes I have, used it in the tent and caravan awning . great , no problems on hookup. it was better than our caravan fridge at keeping things cool.
the second one you linked to is very expensive though .
Mine was this typebut I paid a lot less, got it from lidls for £50 on special offer a few years ago.
if you are going to be paying that sort of price for one , I would recommend a 3 way combicool instead , that way you have the best of all worlds , you can run on gas electric and off the car battery when travelling.
If you always use hookup, cheaper than the husky ones is a tabletop fridge like this
Huskys are Great fridges for camping, used mine in very sunny and hot France last year, no problems.
they are quite heavy though, I have sold mine now on ebay for about £5 less than I got it for a couple of years ago off ebay.
Have a folding camper now with a in built fridge and also an electric coolbox for the beers. I take a couple of bottles of frozen juice or milk in the coolbox which keeps it cold for several days.
