Hi, i have just bought the seals direct weather strip to use on our 2004 Triton 420 gt with kampa air pro 340 2020 edition.It took two minutes to push on, and i am going to leave it on while the van is down the drive, remove before journey and put back once pitched... No need for mallets or anything it just sits on very neatly. Left mine as a 4 metre length and took it past the front and rear gutter drain holes.I was also thinking that when i pitch up i have the awning side ever so slightly raised.
