Safety of Front Engined MH vs Rear Engined

I often wondered if having an engine up front vs rear in a head on collision might be a plus. I was just looking at some of those pictures in the horrific MH crash in Utah. Any thoughts on this?

My DSDP has a diesel gen set right where the 454 was in my old Southwind. I don't think either one gives me a great sense of security in a head on, but I do feel the DP handling is better than the Southwind & might give me a better chance of escaping.

Can't imagine how it would help. In a front engine class A the mass of the engine is below and between the front seats. In a rear engine configuration the generator is in the same position.

Amazing pictures

Article says accident may have been due to a front tire blow out. Questions for anyone who has experienced a front blow out:
  • Looking at the photo showing the MH path from interstate to collision - is this typical?
  • Why would she have not tried to slow? Force of collision makes me believe there was no braking.
  • Heart attack ?????

As we used to say in the old days "When your driving a cabover tractor, if you have a head on, your the first one there".

I can't see where in a moto rhome configuration, you would fair better with a motor between the seats.

If you take an RV driving class you are taught to give the vehicle fuel after the blow-out to stabilize it, then let it slow "gently."

If the driver slammed on the brakes the vehicle might have skidded out of control. Is that what the accident path looked like?

Perhaps traveling at an unsafe speed and probably overloaded ? .. with 10 people on board, cargo plus towing a good sized Jeep ?? From the pictures it looks like a 90's Country Coach Magna 40' DP..... A horrible situation ...prayers to the families.

This works for a rear blow out, not for a steering tire blowout. I have had steering tires blow on a few trucks I was driving and trust me when I say it's a god awfull feeling, it will suck you to whatever side the tire blew on and you can't fight it. Get on the brakes and try your best to slow it down before it sucks you into the ditch or into on coming traffic. Cranking the wheel will only slow it down from sucking you over but won't prevent it. I think what probably happened is the tire blew and before she knew it she was in the ditch getting bounced around and could no longer control the vehicle. I always hated coming onto traffic accidents while driving and always will.... Have seen many over the last 2 million or so miles and it never gets easier seeing them.

imho docj is right.
for most people in a blowout situation, the natural thing to do is to hit the brakes.
it would be difficult to train people to do otherwise. in my 1960 drivers ed classes, thank goodness i was trained not to hit the brakes initially. so, i got a head start.
per michelin, the correct thing to do is accelerate to get the vehicle under control, then slow down gradually.
check this video out.
maybe this post will save a life.

Good video. I never realized that a motor home could be controlled with a steer tire blow out. I have only had tires blow on my semi in the bush on dirt roads and the foot to throttle approach is not practical, as soon as it blows your getting sucked over there is no getting control and pulling over when it's safe to do so. I did have a steer tire blow on a 3 ton cab over on the highway fully loaded and it did not react like was shown on the video. I could not stop it from sucking me over, I never hit the brakes right away cause I was not loosing control but it became quite evident very quickly that it was going where it wanted to and all I could do was slow it down from going in the direction it wanted to.

Front flat, press throttle until under control, THEN slow to stop.

Neither the gas engine or diesel pusher class A's have any safety cage or anything like that. The best thing to do is to drive in a safe and sane manner and try your best to avoid having an accident.

It probable depends if the head on is with a Smart Car or a Kenworth pulling a fully loaded trailer.

Take a look at the frame of a DP. They are pretty beefy and then add the generator. There is a lot more beef in the front than you think. Plus you also have a steel frame around the windows, where some of the gassers have virtually no steel frame for the windshield.

I also believe that insurance rates are a very good indication of accident severity and frequency. Our MHs over the years have been cheaper than all of our cars....oh, except for maybe a sportscar.
