Is it safe to stand on roof?

you could always make sure the insurance is up to date!

I reality, you really need to go up on the roof twice a year and check all the caulking. If you have had the TT for a number of years, you REALLY need to check it. Mine started to fail about 2 years ago. Last year, it felt like every time I checked the caulking I found a new area that started to crack. I got tired of touching it up, so this spring I applied eternabond over all the caulking.

At least for the past several years, Jayco has used 3/8"
plywood, not osb, for their roofs. Also currently, Jayco says their roofs are fully walk-able. I would take them at their word.

At the RV Shows, Jayco is always bragging about how strong their roofs are. Some dealers even had things on the roof trying to prove it. When we went to the races a couple years ago, there was a Jayco Eagle in the infield and 2 guys in lawn chairs with a cooler beside them on the roof. Not sure I'd go to that extreme but like others have noted, if it has a ladder leading to the roof, then that tells me it must be walkable. I have noticed that they do feel a little spongy but, I believe they're strong enough to hold an average person. Not sure how Jayco does their spacing of the trusses. I'm sure not 16 o.c. like a house. Probably more like 18-20" o.c. to save weight.

Not to make you go up on the roof,lol!, but I'd love to see some pics of your eternabond sometime.

I stand corrected on that one. Yes, 3/8" plywood on the Jay Flight, not 3/8" OSB. Sorry. Either way it's 3/8", and doesn't withstand my big @ss as much as the 1/2" did.

My dad has a '77 Jayco. 21'. No idea what the model is. But his roof is very sturdy. No trouble walking on it.

I'm about 6'1" and 255lbs and this "Magnum truss roof" flexed waaaay more than my last trailer that was 10 years old. I know it was the plywood and not the trusses flexing but it was still unnerving. I will mostly likely end up making a carpeted 2x6 plank to distribute my weight onto multiple trusses. I went with Jayco because of all the praise and the 2 year warranty. I have to say so far, I am not impressed.

Yes to both. I am not impressed either with the flexing and crackling our roof makes. And yes, the vaunted "Magnum Truss" was part of my reasoning for choosing a Jayco. I weigh 225 also. The front about 4' from the cap is the worst. What can you really do? Just use caution and hope for the best.

I used 6" Eternabond across the front cap/roof seal. I did an okay job, not the best. I am going to do the rear wall/roof seam, fan, and refer vent next. I am debating the skylight. That thing is so cheap; I can see it failing soon, and I do not want to be up there removing Eternabond. That's the main drawback to the stuff - it's a bear if you have to remove it. I figure the new MaxxAir and refer vent ought to be good for a long while. I am also considering running a strip down the side wall/roof seams. Any thoughts about that?
