There are things that:

Can be done.
Can't be done.
Can be done but shouldn't be done.

I'm just thinking that if something went wrong it would be silly to say it worked all the other times without a problem.

I guess that when folks post things that are questionable just to prove they could do it they are looking for approval. Many folks will slap them on the back as if to say, "Good Job."

Sorry if I have offended but that is how I see it.

ive been launching by myself with class c's for 45 yrs''
vans, trucks,,

I see people jump out at the ramp and leave the car un attended

constantly...

about 10 yrs ago , I bought a new boat in cal.... went to elsinore. to try it out.... the guy from the guard shack co screeming down... the ramp was slick with algee... hes say someone has to be holding the brakes cause it will slide in the water...

I don't know why it's been bothering me , but could see that happening with a pusher.. all the weight is down hill..no brakes on the front wheels

I would say unloading will be no problem, I never get out of the drivers seat...

pulling the boat out ..if I go back as I always do to help guide the boat on
and the movement pushes the motorhome....yikes

we just went down to parker , launched with no problem,,, the mh wheels stayed in the dry ...

but at havasu... although not as steep.. the ramp is sure to be wet....

Friendly advice... DON'T DO IT! LOL

A few other thoughts.

1. There is a good chance that on a longer class A gasser your rear wheels were further away from the water's edge because of the longer overhang. That works into your favor with the class A giving you a bit more of a chance to stay out of the muck.

2. Some Class Cs might also have a tad longer overhang.

3. All things being equal, the heavier DP is more likely to loose the gravity battle if you loose traction. The extra weight on a slick surface probably won't help you gain traction over a lighter MH in some cases. Once the DP looses it, it will go fast.

4. The lighter gasser with the engine up front with only the park break on has less weight on the rear wheels. That actually might have made the situation worse than you thought but being lighter overall the gravity thing might have been an equalizer.

5. I would suggest you NEVER attempt these things without someone you trust in the driver's seat. At least they can add the braking of the 2 front wheels which should be even more removed from the muck.

Listen. I'm not trying to pull your short hairs and in the interest of full disclosure my job was managing safety and devising risk management procedures for air traffic control. I'm anal about it and its in my DNA. I can't tell you how many times after investigating an incident where a pilot or controller said they did it like that all the time and it worked. The problem was that the practice that lead to that situation may not have been a problem but it had a flaw that was just waiting to be exposed. In some cases the flaw of technique/practices took a while to finally bite them in the butt. So, if you are a kick the tires and light the fire kinda guy, my approach will drive you crazy.

It ain't personal.

Would not do it into Salt Water.... Hate to see the frame on a DP go the way of my work truck

Never driven DP but I suspect it has enough weight over the back axle to do it.... depend on the boat as well... would not want to pull out a 20,000lbs boat on the wrong ramp...

thanks for the post,... like I said... we are new to the lauching with the DP
so any advise would be helpful... we are gonna do it... just wanna know the risk and what to avoid....

I see big diesel trucks at the ramp all the time.... do they have front brakes????


am I worring for nothing...the idea is to hear from some one that says it won't slide on the ramp... even if it is wet.. with 16,000 lbs on four locked tires..... what angle would it take for it to slide???

Lanching a boat with a dp class a

Sure, go ahead, no problem! Just run it like your basic F250. I'd do it for sure if I had a boat. What could go wrong? Keep the videos coming.

Great advice!

I'm waiting patiently for all the other folks that do this to post the angles, their pics, videos, tips and experiences. There must be thousands of them.

I don't care how big those back tires are! The darn thing won't float!

Also, if you have someone else in your RV holding the brake down--make sure they can swim--just saying.
