Just thinking of the alternator upgrades that must be used in light refrigerated trucks. I know back in the day when I was fitting my B2B I explored the ones for my MB 616, MB had an OME one with almost twice the output of the factory fitted one.

Runs on 620 watts with allowance for losses, you will need around 3 amps @ 240 a.c.
To get 1amp @ 240 a.c. You will need around 26 amps @ 12 volt d.c. so app 78 amps from your batteries. You dont state what van you have, some pre 2008 vans only had an 80 amp alternator, whilst the a/c will not run continuously it will cycle on and off. At start up it will probably draw twice the current to start if only for a few seconds. If you have two fairly new 100 amp lead acid batteries the most will have is around 100 amps. If stuck in heavy traffic your alternator may not keep up with your requirements. I would get a quote for dash air for your van and compare the cost verses the possible failure of your proposed system.

I can't seem to make up my mind about changing vans. We have had this one for around 12 years, the kids grew up going all around Europe in it. For now it is hard to put out the money for a change. This one was long ago paid for. Newer would be nice though.

I often wonder about a newer van. Mainly for appearance sake but don't believe I would be satisfied with the quality of build these days.

Mine is a hymer S Class (top of range) from the early nougthies on an MB 6 ton chassis. Even got metal taps!!! If anyone knows a company that could renovate the bodywork though I would be very interested.

The van is a ducato 2.8 turbo, I don't know anything about the alternator. I guess for now the weather has cooled down so we have time to think about it.

Ours is the lower end Hymer, camp version, year 2000. But still looks new inside, fabric only slightly faded. We have been doing a bit of upgrading, i finally installed a roll out awning which we never had. I am still thinking it is cheaper to upgrade and repair than buy another.

Brexiters. It's your sh1t now. Whatever happens nationally and internationally you own it. I wish you luck. I think you're going to need all you can get and then some. Friday 13th December 2019.
