I would appreciate any advice on the 'simplest' way to carry bicycles at the same time as the camper trailer.
I've been advised of two options (so far).
1. A double hitch that can fit the camper trailer on the lower hitch and a bike carrier on the top hitch, the double hitch has a 250kg rating and the tongue weight of the camper trailer is 50kg (sold at AutoOne, so meets Australian Standards).
2. Fitting a Reece Hitch receiver to the back of the camper trailer, seems like a simple solution, however I've been advised by numerous towbar places in WA that they won't do it as it is illegal and they only have legal set ups for caravans (I guess they'd know the legalities of it?).
I don't want the bicycles on the top of the car.
On top of the camper trailer?, unless there is a very simplistic system for the top of the camper trailer, as currently for a quick set up and flip out is 5min, having said that most of the time would be a full set up, so an easily removable setup.
Getting to the desperate stage now as I have no ideas, I'm thinking that you've seen enough things out there to give me feedback and tell me how EASILY this is solved

Fingers crossed.
