I was told that to get a blue slip in NSW for a camper you need an engineers certificate for the pop top because its a modification.
Sounds crazy to me.
Has anyone else had this problem?

Who told you that?

The mechanic.

If it dosent have a compliance plate from an approved installer, Sopru, Trakka, Sunliner, Doormobile, ect, or an RTA approved engineers certificate, you have to get it one. I installed a pop top out of a sopru conversion, into my panel and had to get it looked at and approved by an RTA approved engineer, for it to pass rego, no butt's about it if you get pulled over by the cops, or RTA inspectors, and you dont have it complianced, (cert or plate) it will get a yellow sticker (unroadworthy) and thats it! if you want to know more U2U me and I will give you my PH number.
Rob....

Of course, any structural mods need an engineers certificate...

Even different seats need one...

That is why nsw have the cleanest and safest vehicles on the road...

Interesting info!

My Sopru camper never had a 'camper' compliance plate; just the usual VW one behind the driver's seat. Nor did it have any gas fitter's tags or labels anywhere.

However at least on my rego papers the vehicle is classified 'MH' - for Motor Home.

I must ensure the old girl never goes out of rego at it has been completely rebuilt and is certainly no longer 'factory original' - considerably better in fact.

Sopru's didnt need gas or lecck tags, they had licenced PPL doing the work and were complianced under the one modification report, I have a sopru tag here I got out of a wreck

my trakka has a compliance for seating 3 people. does that include driver?
also, as i have had it off road, can i prove that it was registered with all mods previously (poptop, rx3 front seats, camperised, gas fittings, engine conversion to subaru etc..)? will detail photos of it registered help?
