Hi, although I've been a motorhomer for many years I'm new to this site and I'm hoping someone can help me. I'm about to buy my next m/h, a Burstner Nexxo t720, and I want to carry 2 ebikes on the back, each one weighs 19kg without their batteries. The new van doesn't have a fitted bike rack but does have a toe bar. I'm thinking of buying a tow ball mounted rack, but which one? I'd appreciate any suggestions
