A quick check indicates the rear bumper will drag at about 15 degrees so to get 20-25 degress of leveling, the tires will need to be on a slightly over 12" high platform. I have no practical idea on how to accomplish that feat.

Sell the trailer if that's the best you can do. Sorry. But a 25 degree slope is not an option.

I guess I assumed wrongly 5 degrees = 5%. How is the "% grade" figured?

If you try it watch out you don't get the stabilizer jacks or anything else on the belly hung up and rip them off.

I don't remember a whole lot of the Physics classes I had years ago in college, but since a 25 degree slope is about the same as the pitch on the roof of my house, it seems to me that there is going to be about a 1,000 lb forward force from the 3000 lb trailer just due to gravity. I think it will roll right up and over about any type of wheel chock you would put under it.

Also, even my trailer drags the rear bumper a little getting in/out of my relatively normal driveway so I don't think you can back into a driveway like that. The rear bumper will hit, and even if you have the horsepower to continue pushing you will just lift the trailer wheels off the ground or wreck your hitch.

I know you mentioned money is tight, but you already put out a pretty decent chunk of money for a 2005 model so you need to find a proper place for it and I really do not think your driveway is it. I also cannot store my trailer at home (due to Homeowners Association --the neighborhood nazis) and for a while I had it at a "Public Storage Lot" which I didn't like because it was too public. I now have it at a year-around campground 60 miles away.

So while it would really be nice to have your trailer at home, my suggestion is to be open to various options and be willing to look a medium distance outside your neighborhood if you have to.

regards, Dave

keep this figure in mind...

a 45 degree incline is a 100% of grade...

i think.

it's really high school trig.

% of grade is a tangent related to rise over run...

there are tables for these tangents and calculators have formulae that can do the duty...

here are some incremental examples of the the 3 concepts.

-1 foot of rise over 100 feet of distance is a ~1% grade or .6 degree angle...
-1 foot of rise over 10 feet of distance is a ~10% grade or a 6 degree angle...
-1 foot of rise over 4 feet of distance is a ~25% grade or a 14 degree angle...

-1 foot of rise over 2 feet of distance is a ~51% grade or a 27 degree angle...

which is one really STEEP driveway!

the problem folks get into is saying 'percent grade'

when they should be saying 'percent OF grade' which makes it all clearer...sort of

anyway rise over run times 100 is the 'percent of grade' or rise/run X 100 = % grade.

road inclines/declines are usually? described in % (of) grade not degrees of angle.

so the op with a "20-28 degree slope" has a 36-53 % grade driveway...YIKES!

this is crazy steep (if true), and would take a significant amount of power/force to get up...

then forget about 'leveling the trailer' they're gonna need an anchor and chain, frame mounted and...

rated to something like 8-10,000 lbs + to keep the trailer from rolling down hill...

and a LOT of traction and power to get it UP there...

or they could build a scaffold under the trailer once it's up there and launch it like a boat, see the picture above.

cheers

Exclamation Don't

This sounds very dangerous! Even just driving or stopping on so steep a slope with a trailer is challenging. Even just parking is risky, and uncoupling downright suicidal.

The trailer will likely bound over wheel chocks. I've had even triangular wheel chocks turn upside down with far less provocation, not to mention jackstands tipping and jacks tipping or failing by bending! Your hands might get mangled by the coupler, the trailer might gore you against your tailgate, and there is the whole trailer and possibly tow vehicle rolling down the driveway into school buses scenario to consider too.

The hills of Oakland are nice, but they aren't for trailers. Sorry.

How about hitching to a dead man post and winch it up? or a tower crane?

Do you have any neighbors who (a) have a possible place to park your Bambi safely and who (b) like you enough to do that for you (maybe offer to pay them a small fee if necessary)? There might be insurance issues, but it's a thought. You don't want yout trailer to get away from you on its own nor do you want to risk injuring yourself or someone else with it...

Keeping your lovely Bambi in a rental garage (can you go into Lafayette, Orinda, or Moraga?) seems a lot less threatening than parking it on that treacherous driveway.
What do you think of all these alarmed responses?
