I've owned
cars with suicide doors ... I've owned (and currently own)
vintage trailers with suicide doors ... I've built
teardrops with suicide doors ... and while my
preference might usually be for the non-suicide doors (for all of the above stated reasons), I am
not afraid to build & install them in either of the vehicles if my sense of style and aesthetics deem that it would be desirable to do so! If you think your trailer (teardrop or otherwise) would look or function more to
your liking with suicide doors, then do not allow the nay-sayers to sway you otherwise! Yes, there are (small) challenges to sealing and securing this style of door, but they are easily surmounted and you can feel at ease and be secure in the knowledge that it/they will NOT leak and NOT fly open while going down the highway! Bottom line ... if you
want suicide doors (for what ever reasons), then build & install them ...

...! If you think you want or need advice on how to do them correctly & safely, send me an e-mail of give me a call!
I've told this story here many times ... Li'l Bear #01 (built in 1984, BTW) has an all-glass door on the right side, and it is a suicide type door ... on its very first outing, it came off the hitch ball and snapped the safety chain, and at over 60mph, drifted off the road and struck a concrete bridge abutment on the right front corner, then ca-roomed back across the freeway and buried itself in the oleander bushes in the median ... there was minimal damage to the trailer, and even though the door was NOT locked, it did not come open, and the glass did not break!
Now, for a lot of reasons, all of my
production trailers have had (and continue to have) the typical forward-hinged doors, but if a customer specifies they want suicide or if I choose to put one (or more) in a custom spec build, I am not afraid to do so and will gladly oblige ... no fears, no worries, no ifs-ands-or-buts about it ...

...! Good Luck on
your build, and as always ...
CHEERS!
