I need towbar buying advice - Mk III V70

[Jaz167]

Before I commit to buying a towbar and electrics for my recently purchased Mk III V70 I'd appreciate the combined wisdom of those who've been there - done that.

I'm also on the look out for a caravan and erring towards twin axles at the moment for size and (at the risk of triggering a debate) stability.

Mines a D5 geartronic and, from what I can tell, the best of the V70's for towing allowing for 2000kg and 90Kg nose weight (on both the V5 and owners manual)! Don't worry, I aim to be within that with a absolute maximum 90% ratio.

Driving licence restrictions are not a problem for me.

So, what towbar should I get? I don't want to spend too much and was inclined to go for a fixed one like a Witter. Apart from aesthetics is there any advantage to the retractable type? Is the Volvo bar superior enough to justify the price? Is it better to go second hand Volvo / retractable rather than a cheap new fixed?

What electrics? I'm assuming everything will be 13 pin nowadays. Should I get an aftermarket kit with relay etc that fulfils all the legal requirements but doesn't interface with the manufacturer set up or a Volvo kit with the module etc. Which is easier to fit? Can someone with DiCE/Vida complete the software update if I go down the Volvo route? I do like the idea of it being integrated but is it just over-complicating things?

On the subject of fitting I'm inclined to do it myself. Not just because of cost but also the confidence that it's been done properly. I guess the holes are already there anyway and it just needs attaching?

I might leave the electrics to someone else unless you can tell me it's not that hard?

How have I managed to turn a simple question into such a long post (don't answer that).
