Need name for mods to jayco swan in Brisbane

Hi,

We have a Jayco Swan outback that we need some modes done to. We want to have the jerry can holder removed and replaced with Dual Gas bottle holders, also considering mods at the rear, removing the bumper and putting metal boxes on the back and then replacing the bumper. I'm looking for help locating the right person to complete this type of work in Brisbane. Also any advice regarding the boxes at the rear - looking for tips on what we should do there. Thanks in advance for any advice

regards

Graham
