Use perfect multi gym on mobile home door frame?

[Parks 788]

So I'm in the process of trying to get in better shape so I bought the perfect multi gym (door frame mount pull up bar essentially, the no drill version) and am curious if y'all may have used one or have an opinion as to whether they would be safe to use On a trailer home door frame? I spend a lot of time in one for work which is when it would become very handy...but I'm right around 210 lbs and not sure whether a trailer door frame would support me, what says you OSA?

Only asking because I'm curious. YOu said yo uwant to get into better shape. Me too as I'm probably 50# overweight. I can't do a pull up. Close but no cigar. At 210#s can you do enough pullups to make it an effective workout? Start small and work up to more reps? I'd like to get myself a TRX system. Had them in a gym i went to years ago and they were great.
