Hi all
A report back after last weekend's camping trip; what this set up was bought for.
Roof bars were simple to affix after doing it once already, 5 minutes max. The soft roof box is a little more tricky as it's quite a manual job turning the plastic thumb tighteners and lining it all up evenly, probably about 10 minutes.
On the roof I fit a 17kg steel frame tent (Vango Calisto 500), a 36l coolbox weighing about 20kg. Then a few lighter things, roll up alu table, camping chair, picnic blanket, folding water carrier, and a bag for life for of camping gear. Total weight about 43kg.
In the car we packed a W60xH30

36 plastic tub with all the cooking/eating gear and dry foods. Another folding chair, double airbed, small folding table, big bag of clothes for us, and a few odds and sods in the little bits of space left. The lid just about shut
Baby girl in the back, buggy (3-way fold Quicksmart Easy Stroller) behind mummy's front seat, collapsible Samsonite bubble cot bed, sleeping bags, blankets duvets and tent carpets all stuffed down next to baby Summer, plus a big bag of her provisions and clothes, and our day bags.
It all just fit perfectly

. Driving was kept to 65-70, for 2 1/2 - 3 hours
on the M56, A55 and a load of windy roads to Tudweiliog. The driving experience was very stable, but obviously I wasn't putting it through corners as normal (I have a heavy right foot), the whole setup didn't budge a centimetre. Only thing that was noticeably different was braking and acceleration up hills. As if the 1.2 wasn't a lurcher as it was, so it needed driving quite hard to get up to speed or ascending hills.
As I was too bust trying to get going, and putting the tent up, I forgot to take my usual salvo of pictures, but my wife did manage one while setting up that shows just how freaking cool the 500 is, and ironically the 500 tent that should have no business being partnered with it

.
So here we are setting up (dogs and cool box in background not mine).
Setup and enjoying a booze (note all the kit that we took with us!)

So, massive success and we're all ready for a longer trip to Latitude Festival in Suffolk next month.
