    349m Roof Weight Limit

    ok - I'm fat. What is the capacity of the ladder and roof on a 349m?

    From my research, I have seen it being 300 lbs on the ladder, and no restrictions on the roof, even the slide outs.

    As stated, 300 lbs. for the ladder. If you're concerned about the sheathing on the roof, you can put a couple of 6' pieces of 1 x 8 up there and shuffle them ahead of you as you walk. That will distribute your weight over a wider area than just your footprint.

    I just took delivery of my 320G, and the ladder has a sticker saying the weight limit is 250 lbs.

    I have a 28G Momentum, I would imagine the roof capacity is similar if not better on yours. I weigh 255# and walk on mine with no issues. Concerning the ladder, I have used mine with no issue but prefer when possible to use a normal ladder.

    Thank you for the responses. Unless I have to I'm going to not venture up on the roof. I've got 2 teenage boys that are more spry then me.

    However, I am trying to lose some of that extra baggage and someday make it up there.

    I have managed to collapse an rv ladder before... The rungs are held by plastic inserts and what appear to be similar to drywall screws.. I was lucky i wasnt near the top and was able to grab on. I was also a lot younger at the time too. I was pushing 250 at the time.

    I was able to fix the ladder, had to beg for spare parts at an rv body shop where they had a twisted busted old one in the trash as when I tried to get the plastic inserts they could only "sell" me a whole ladder at parts...

    I have since taken to using a regular ladder to get up and down when at home. If we are out and about I send the "boss" us as she is half my size. We pnly go up if there is a problem or if we need to sweep leaves/needles off the slide out before running it in.
