Default Need help identifying roof type 2007 139

Greetings FunFinder FamilyÖ. Attached are pics of our 2007 139 Funfinder X. Just trying to figure out if my roof is Topo or the other typeÖPoly?? Itís not leaking I just want to know for future maintenance/replacement if needed. Also no leaks on windows but I noticed some separation on exterior seems and little on the interior bathroom behind toilet. This is the caulking the RV place suggested I use but I wanted confirmation from the Veterans on here if possible. Secondly, Iíve never been able to make TV antenna workÖ. It appears in perfect shape, the TV is very old, the red light on the button on the outlet inside trailer pressed and working, select cable functions on tv and just no channels. It works great when connected to rv park cable just canít figure out the darn antenna situation.

RE: roof material type, I believe that the roofing on the FFs of your era were/are EPDM (ethylene propylene diene monomer). Any caulking that you might use should say that it’s approved for use on EPDM material. Your local RV center should carry such a product. I paid about $10/ tube for mine.
RE: your roof antenna, you didn’t mention so I have to ask, did you crank the mast up into the vertical position? The mechanism that operates the raising and lowering is located inside the cabinet just above the dinette. Once elevated, I believe (I’ve never connected my tv to the antenna ��) that you can rotate the antenna to get the best reception. I don’t know if the factory installed antennas (antennae ��) are tuned for digit reception but for sure the TV must be “digital” or use a digital to analog converter.

Thank you for the EPDM clarification on 2007 139. Iíve read how to take apart an inside vent or peal back something on the outside to identify type of roof which I just donít want to doÖ. The antenna I have cranked up but wasnít aware it may rotateÖ also wasnít aware TV must be digital. My (very old) TV is wired into the CD player which plays cd disc movies which is great but itís just never picked up any channels even in middle of a city so I may need to upgrade although I really probably donít need it. Really appreciate the response and Iíll study and maintain accordingly.

Actually, I would lean towards TPO (thermoplastic olefin) that's what mine is. A TPO roof weighs less than an EPDM roof and FF was going for light weight. To tell for sure as you said remove the inside frame of one of the vents and you'll see the edge of the roofing material. If it's black on one side it's EPDM if not it's TPO.

The sealant you posted appears to be silicone which is not typically recommended for RV exteriors because it doesn't stand up to constant flexing, can't be coated over because nothing will stick to it once cured and it's nearly impossible to remove.

I know Geocel makes caulking specific for RVs so you may want to check their website to verify. My personal experience is with Dicor which will work with either TPO or EPDM but there's other brands like Eternabond and Proflex which are good also.

If your TV is the original from 2007 then it's an analog type. In 2009 the US converted all TV broadcast signals to digital so the old analog style can't pick it up. Out of curiosity I did a google search for digital/analog converter boxes and you can still get them for around $20 or so.

I’m of the age where not every little detail of my past has a dedicated storage spot in my brain. That said, I’m pretty sure that the roof material on my’07 x210 is EPDM. I vaguely recall looking at the underside of the roof material when replacing the main roof vent. As described in the video posted by Eagle, a black underside indicated EPDM. LJAZ suggested TPO because of its lighter weight but I’m not so sure that the CruiserRV FunFiinders of the OP’s vintage were all that concerned with weight (at least not as the RV builders are these days).
IMHO, RE: the OP’s query as to what “caulk” to use, I’ve used Dicor brand self-leveling lap sealant with good results. Better still is that it’s recommended for both EPDM and TPO!
