Just looking at a list of things to order from the factory with a new Plus Four. Would welcome opinions about factory vs aftermarket alternative, for:

- luggage rack with side screen stowage (LiBrands is cheaper and as good as factory design? It looks a little leaner too which is a good thing)

- battery conditioner - any advantage in getting the factory-fit one or are there better options?

- outdoor/storm cover - I've seen recommendations here for Richbrook - how does it compare with the factory one?

- luggage rack straps - look good but should I get one of the more modern hard-to-cut options discussed on these forums instead?

Thanks
