Does anyone have experience with how far (what angle) you can tip a C250WK that is on the factory trailer without going over?

I need to put my boat in my driveway (OK, it is a dirt road, driveway is a little too uppity a word) this week. The road in front of our property is not quite wide enough for me to get the trailer completely lined up with the driveway before it starts backing down. This causes one side of the trailer to start descending before the other, and creates tipping. I have done this several times with just the trailer, but this will be the first time with the boat on it. I would hate to dump the boat on its side in my front yard.

Any advice?

You would have to get it pretty far over. A little help from Arlyn on this please....The keel is going to offer substantial weight down low which is a good thing. I would guess it would take something in excess of 30 deg. The Factory may have a exact info as they offer the boat with a trailer.

Tom.

Kevin, Without seeing your situation is it possible to disconnect your tow vehicle, line the tow vehicle up straighter and reconnect to the trailer and back in straight? Have done this many times with BIG Army vehicles with trailers. How about pulling straight in and backing out? Good Luck.

keep in mind that while there is 1,000 lbs down low in the keel, there is yet 4,000 lbs of boat above the keel. One of the problems of slopes, is the weight will track the trailer much farther downhill than it would normally track... that may or may not be a problem.

This seems to be one of those instances where unsureness exist... when unsure and life or property risk intersect... I DON'T.

Kevin, I have a similar situation with my drive way. I don't know if you can tell from the pictures the angle of the slope I deal with.

Tom, your slope looks about like what I have to deal with. Because of the narrowness of the road in front, I can't get my tow vehicle in front of the trailer, even with the thing jacknifed at 80 degrees or so, before the inside trailer tire starts to go down the slope, tilting the trailer inside the turn. Do you have to same situation?

Driving in and backing out does not seem like it would change the situation, I will think about that.

If I really got desperate, I suppose I could use the tow vehicle to get the trailer lined up with the driveway, put down my new third wheel, then use a winch from a tree across the road. Now THAT would be a pain. Even then, I am not sure it would work.

I guess I will try it with the trailer only tonight, and try and determine what the maximum angle will be.

Tom, what angle does yours tilt to.

Thanks everyone for your replies.

Gotta take pictures of the third wheel this afternoon too.

I pull up parallel in front of the house and have to cut the wheels sharp to start backing down the driveway. The truck is never straight in line with the trailer all the way down. Yes it looks like its going to turn over on the way down. I have no idea what angle the boat tilts at since I'm all puckered up behind the wheel of the truck the whole time. On top of all that I have to use 4 wheel drive to pull it back up.

Tom, I went out and did some experimenting with just the trailer this evening, and I learned something.

When I start backing into my driveway, the trailer is already moving on a downslope due to the crown of the road. That makes the mast raising mast look like it is tilted at a crazy angle out the back of the SUV (when the tow vehicle is nearly 90 degrees to the trailer), but almost all of the tilt at my place is downslope, not left or right tilt. I put the trailer in the worst spot andthen stood on it, and I could barely detect an angle. I hung a weight from the top of the trailer mast and I would estimate the angle was 5 degrees or so. But if you look out the back window of the vehicle, it looks like it is tipped 30 degrees or more.

So, I guess I will give it a shot later this week. It will either work, or I will have some interesting pictures...

Speaking of pictures... don't forget to get some of that launch wheel.

Ya I know. Ever work your butt off, barely getting everything done in time for a trip? That is me right now. Sleep deprived.

Will do pictures soon.

Will try it out this morning.

One thing that may help is a front mounted receiver hitch. It turns in a completely different way. Also, it is not a great idea to put too much pressure on the rig while in reverse. The ring and pinions on your differential try to spread apart when in reverse. Also the reverse gear in the tranny is not that strong. I learned this playing around off road.
