Thanks, hubby is a joiner by trade and is fairly handy at diy/fixing cars etc. so should be OK, it was just me that needed re-assuring ha! ha! thanks again !I fitted my Rhyno Lite Mover last year. Took around about half a day and was fairly easy. You do have to crawl about under the 'van to route cables and secure them, so getting the 'van high enough to do this easily and safely was probably the most difficult part of it. The Rhyno instructions were not particularly clear and some common sense is needed and the correct tools, but shouldn't be beyond the scope of a competent D-I-Yer. You may have to drill a hole in the floor if an existing one is not available and also a hole into the battery box for the power cables. Other manufacturers instructions seemed to be better and you can see some of them on manufacturer's websites which will give you an idea of what's involved. I thought one of hte best was teh Enduro instructions at www.purpleline.co.uk/Enduro/Images/EM103 manual UK 06-07.pdf. There are previous threads on this subject which also may help.
I've fitted the Enduro one myself with no real problems and as Ray says you will also have the knowledge then of how to transfer it to another van if/when you change. The only worry I had was driling the large hole (approx 4cm) in the side of the van for the isolator switch. I'm not sure yet how I will cover this up when I do change.
Thanks that's interesting.I also leave the battery box door open just incase !!No the Enduro one I have definitely says to fit on the outside for safety reasons. It is much wider diameter than the one shown, and surrounded by a watertight case and flap, a bit like the water input box. Having said that, I wish I had ignored the instructions, followed my first instinct and done what you suggest. Perhaps if I move to another van I'll just leave the empty case and buy another isolator to fit internally.
