I’ve got them, had them sorted at grippa tank, and guess what, I never use them
Seriously, never actually use them, always just have the van door open.
Nice to have for the times I might be in a rougher area though...
Interesting you say about efficiency Jonny, my setup is similar to yours, and I find it quicker and easier to open the rear door, pull the pole out, grab the hose and walk off to the house .
I actually find it slower putting my hand under the van and getting to the hose. It’s also a lot more resistant when under the van/more faff catching on my tyres when at an acute angle.
