dragging on steep hills

I have a 1975 23 foot Safari with the rear bath. The driveway to the house where I keep it comes off level road surface and then makes a steep bend up. I pull the Eazlift hitch and replace it with a longer drop hitch and the trailer still drags the rear of the frame and the black water tank outlet as the rig articulates on the slope.l I've had to replace the outlet cover twice and install a new outlet once. I'm sure that if I keep doing this, eventually it will crack the tank. I can only drop the hitch so far before it starts dragging the jack bottom at the front. I would like to install a set of rollers as in this illustration http://www.airforums.com/forums/f44/...s-56859-3.html. I've considered putting a rubber nose wheel on the jack bottom as well, but I doubt it would stand up to any real stress. Anyone have any other suggestions?

Ramps

I would think you would damage the frame of the trailer if you in effect lift it by the rear. I would consider building a pair of ramps that would smooth out the "V" shape of the incline. A couple of 2"x8" boards with a support block or two in the middle would work.

I'm concerned that once a lot of weight is on the rollers and the trailer is lifted at the bumper it would cause damage to the shell. Kinda the opposite of frame separation from the rear end dropping.

How about replacing the axle's to gain more drop angle, or fabricating a frame block between the frame and axles to gain a few inches. Too much of that will be horrible for looks & aerodynamics. But if 2 inches might be just enough.

We had the same problem in our driveway. Went down to the local bigbox and purchased 2 lengths of 2x10 decking stock and made our ramps (they are wide because we're on a cul-de-sac, and have to come out an an angle). Anyway, the doubled up area sits in the lowest area (basically the "v") to help with bending.

I agree with the other posters.

We had a pretty similar problem with the drive at our old house: A BIG notch in the driveway would cause the rig to bottom out. Problem solved with a pile of old boards, stacked side-by-side to raise the center of the notch by six inches or so.

HiHo! That's a dead end street! Cool photo though. I'm finding I have to think about approach angles more with the 30' than with the 25'.

flyfshrman,

If it's your driveway or one belonging to a friend you may be best off paying to have it graded (assuming it's gravel or dirt) and maybe even have a load of fill trucked in.

Often an hour or two of machine time is enough to solve the problem.

Installing rollers will damage the 2 rear quarter panels, GUARANTEED.

You can increase the width of the rear drag plates, which will help.

Also, your axles may have had their rubber rods go south. If that's the case, replacing the axles will help, along with increasing their starting angle.

Andy

I have the same problem with my driveway - too steep to either back or pull her up. I first tried backing up and the guards on the bottom of the bumper dug into my driveway (asphalt). Then I tried to pull her up and the tongue dug in. So when I tried to back it out - the guards under the bumper dug into my street I did get it back onto the street, but not without leaving some divots.

I gave up and rent a spot at the local storage facility. Not my first choice, but I don't see a way (other than regrading my driveway) to get my silver swan onto my property.

Any thoughts on overcoming this without the need to redo my driveway are appreciated.

patentguy, did you try the driveway without your WD bars? Sometimes it doesn't take much to help.

Andy made two good points for the OP; his '73 may be at the age that the axles have begun to sag - thereby lowering the rig. The second point is that installing rollers is the same as jacking the rig from the rear - bound to stress the back end. However if you install a wider drag plate, the stress is spread and may be enough to permit dragging when entering and departing.

If the slope of the driveway is reasonable, I would check the axles first. New axles will give you up to 5 inches of clearance, presuming yours are shot.

I replaced the axles on our 27 foot 1969. We raised the trailer 3 inches at the rear tire from the floor to the trailer. So I dont know how much it raised the rear end. Ours was close to the ground but now it is not. Because our axles were shot. We bought our axles from Inland RV. It was pretty easy to put the new axles as I did this myself but had to have help with taking the old axles off.

That's really a fine looking road grader you have there.
