I have searched for quite a while now for
Biggar window seals , Apparently there was a company by the name of storm tite in Alberta that made the seals for Biggars and Triple E motor homes , a fella by the name of Manitoba Paul was able too get seals thru them years back , They are located in the States now , I sent them pictures of what I was looking for , they didn't have them anymore I was told , no doubt they ended up in landfill when they moved . VINTAGE trailer supply had slide track and the fuzzy felt but I have looked for quite some time now trying to find outer seal, I am no window expert and don't Know if something could be substituted . if I find something I will post . Kind of a dilemma . if you want the black plastic 1" wide Black vinyl insert strip for Bigger exterior is an airstream part and the only one that fits , others
fall out as they are metric , Vintage trailer supply carried it but since covid Unavailable . I bought some thru Airstream in States , around 50 bucks , it was shipped UPS and cost me 200.00 shipping and border fees , never use UPS , Vintage trailer only cost me $75 I believe . expensive lesson . hardest part to find for a
biggar is window seals , at least for me . I found door seals on Amazon .good luck .
