Securely mounts onto the towball so can be used on most cars / vans . Easily removable so doesn`t have to be permanent and could be transfered between vehicles if you want to . Haven't used on my camper as it doesn't have a tow bar but i`ve seen them used on T2/25/4 and 5`s Folds flat for storage and has all the correct arms /straps for securing two bikes . Looking for £60 . Collection from Teddington (SW That London) or possible delivery to techenders .
