Congratulations and welcome on this site!
I have a 1986 15B17G.
There is very little documentation on Bigfoot
I was told that the company's premises had burned in 2004, I believe, and that they had lost a lot of documentation in the fire.
They took the opportunity to remake new molds, larger, series 25B17.5G.
Members of long dates will be able to give you the history in details.
I have already contacted a manager at Bigfoot to get information about different items in my Bigfoot and he replied that when the trailer is delivered to a customer, the same customer may have made changes and you could be directed in a wrong direction ...
So, at that point, I understood that if I have questions, I analyze the problem myself, if I do not find a solution I question on this site, help with problems encountered and more
I go to a specialist, I do not take luck with this item.
When I bought my Bigfoot 3 years ago, there was a propane
detector but several years past the deadline, enough that the owner did not know the usefulness of this detector, to say that...
It is well to get a list of all the items to check and proceed step by step ...
Have a good day,
