Fixing to a Habitation door Elddis Solid construction.. (1 Viewer)

Hi, I have a 2015 Elddis built motorhome. The habitation door is only single point locking in the centre. I have sourced some Fiamma safe door Guardian deadlocks, the catalogue number is 29534. They simply fit on the inside of the door with 3 screws. I am concerned regarding putting self tapping screws into the inside of the door. I don't actually know what the material is, it's GRP on the outside clearly I wouldn't use anything more than 12mm in length. I have toyed with the idea of fixing a plastic doubler, say 3mm with one of the high bond adhesives then some adhesive behind the lock and then the screws. I realise fitting them top and bottom will only make the door about 30% stronger with regard to a burglary but it's better than nothing, in my opinion. Any bright ideas are welcome.

Looks like you got it sussed, probably the way I would go with the plastic Packers

Hi, thank you for your thoughts, it's nice to get another view on a problem. Clearly I could put bolts all the way through but that would be bonkers. I hate screwing into the walls etc.
Have a nice day.

All done, had a better idea for a doubler and used 1.5mm alloy plate, fixed same to plastic on inside of hab door with Very High Bond double sided tape. Had to change bolts as well as the Fiamma door guardian were not suitable. Used ScrewFix 150mm Chrome heavy duty bolts, only £4.00 each, a fraction of the cost of the Fiamma ones. Fixed bolts to alloy with 25mm x 3mm dia self tappers, got a good fixing. There is very little to screw into in the inside of the hab door, so the alloy saved the day. The result is we can slide the bolts over at night when we are sleeping. Some motorhomes have 3 point locking on the hab doors but sadly Elddis don't go to that expense. Feel much better now with the bolts top and bottom.
