Like most vans we had no spare wheel for our Adria Coral 670SL. I have managed to aquire a spare wheel (16" x 175). Bit of a beast and weights a ton second hand but dont really want to put it in the garage as the weight limit is 150KG. The rear has a bike rack so no go. I am not a DIYer so can anyone recommend a company who can undersling the spare wheel safely on my Adria. Your comments would be much appreciated.
