It's double sided taped on then held with silcone. I have a clip made up for the lid and the boss was a little enthusiastic filling it but I reckon it'll stand up as well as anything Jayco attach. The jtech rides the corros better than any leaf sprung trailer we have had so with 4 tyres at 20psi reckon she'll be right?
Interesting I put the number plate on with super dooper double sided tape when we bought it. As I wanted to relocate the number plate one day and didn't want the holes. The damn stuff is so good I can't remove it without totally wrecking the number plate!
