Dennis,
You may already know this, but just in case someone else doesn't, here's a great way to search for information on a website, including our forum. I find it more effective than the forum search function, and more flexible.
As an example, let's say you're looking for information on "sealing roof and windows", and want to search the forum for threads that have such information.
Simply go to an empty tab in your browser and type "sealing roof and windows" followed by "site:." followed by the website you want it to search, in this case, "www.hilotrailerforum.com"
Without all the quotation marks, it looks like this:
sealing roof and windows site:.www.hilotrailerforum.com
The text in red, "site:." is the key, and of course I just typed it in red for emphasis. Those 6 characters go between the topic of interest, and the website you want to search.
Click "enter" and you'll get a bunch of threads about "sealing", "roof", "windows", etc. Play with it a little bit.....just type
"sealing roof site:.www.hilotrailerforum.com" and see what you get.
Or, try "best caulk site:.www.hilotrailerforum.com"
It's really quite easy.
Hope this helps.
