Fitting of water tank sussex

Got myself a xline 350l DIY system.   Need it securly fitted to chassis but I'm struggling to find any garages even willing to do the job.  Based in Horsham but willing to travel if anyone knows of a fitter I'd appreciate the help! 

Try the cleaning hub in Hailsham I'm sure they supply and fit systems so could be able to help you.  Be careful if having the tank bolted to the chassis as by having holes drilled through may fail the mot if the inspector thinks the chassis has been weakened.  You can bolt the tank to the floor if spreader plates are used. Also always best to make sure high tensile bolts are used.
