Luc don't bother, you will regret it. Truckmount hose is made to a specification... to avoid pinching up under the vacuum loads generated by a TM !!!!!!!
I bought a length of the "flexible" hose mentioned above and my TM ate it for breakfast. It was fkin useless.
If you're running a 2" wand you just have to get used to it, it really isn't that big a deal, you just come to terms with it. However in tight spaces I still use my 1.5" wand with 5ft of whip line, admittedly there are some parts of jobs you just couldn't do with the 2" hose straight on to the 2" wand.
