As you can see from the picture below, we have a 3 piece fence in front of the annexe to keep our labby safe and secure without tying her up. The fence panels are from Bunnings and are the 2400 by 900 high. The have been cut back to 1900 for carting purposes with joiners to take them back out to 2400 when they are put up. The panel at the front has a gate cut into it to allow easy entry and exit.
Up until last weekend, we had been putting them inside the van, wrapping them in the bed quilts and securing them with straps in front of the fridge. Getting them in and out turned into a monumental pain especially when wet, trying also not to scape any of the interior as we went.
Having read much about bike carriers failing and not liking the idea of fastening anything to the Expanda lid, the idea of mounting the racks on the bumper seemed the way to go. The racks need to be removable otherwise the back lid can't be opened. Hence the two 32mm tube mounts bolted through the bumper with 8mm bolts. The uprights plug into the bumper mounts and for good measure, the tops are secured to the top ridge through the use of marine canopy fittings. These are bolted through the support beam in the back and if the bumper fell off, the top supports would support the rack and load. Four straps secure the fence panels to the racking and then there are two more straps which hold them in further using the grab handles. The bottom mounts have two horizontal sections to allow the uprights to be stored off the ground when the rear lid is up.
The welding was the dearest part of the exercise followed by the powder coating. Another project done and dusted and couldn't be happier with the outcome.
