>In practice sessions at rallies where emergency procedures are rehearsed, it's difficult enough to get out of an RV from the escape window, considering it's height from the ground, but if a fire broke out and your only escape was a roof opening, your life could be in peril.<
Thanks for the reminder. I appreciate your bringing it to my attention.
I've tried both. You are probably thinking of the fifths that are made these days with full-height bedrooms. It would be a challenge to get out of that without a ladder, I am sure. However, our fifth has a half-height bedroom. I find the roof hatch a whole lot easier to get out of. By just standing up on the bed, you are over half way out of the unit, and fully supported on your feet as you do so. Getting out of a side-mounted escape window means scraping your belly on the rather sharp lip of the window as you dangle your feet in mid air, then fall over backwards once you do hit the ground. One can always shove a blanket out over the edge first, and reduce the discomfort, but that takes time and presence of mind in an emergency. It is also 'slippery' when trying to control the speed at which you exit.
There is nothing to hang on to in order to control your descent. You see, I have thought about it.
The top of the escape window in this unit is 4" from the roof. I don't see 4" as making that much of a difference in height between a side-mounted escape window and a roof mounted hatch. If I am wrong here, then let me know. But, as I said, I've actually used both (though not in an actual fire, fortunately). I really find the roof hatch is much easier to use, and you have much greater control when exiting.
In any case, there is nothing to prevent me from having both, I guess. If my experience and reasong here are faulty and this is still an important issue, then I can leave the side-mounted escape window in place. I still would like to have a roof-mounted escape hatch / ventilation cap / skylight combo in this trailer. Do you know if such a thing is made for the greater thickness of the newer domed and trussed roofs? If so, I might consider one for the rear of the trailer as well. The lower bunk where my daughter sleeps has an escape window, but the upper bunk does not.
