It is just the way the forum is set up. The Sub forums are not just dedicated to an owner of a certain make To the right are any recent discussions and unless we scroll up and check on mine it also says travel trailers and fifth wheels.
Water heaters, plumbing , electrical, etc. etc. are similar make to make, if you have a R pod only question state so in the bold title. Otherwise you will will responses from anyone and everyone like me. The FROG forums are for every FR product and not truly separated as such.
Motorhome people have gotten upset because trailer people answer them too ......
