Why ? trailer jacks so tall ?

I never had this problem with a standard electric jack and Equalizer WDH on an 2003 R-Vision Trail Cruiser TT by Monaco Coach. No modifications or extensions were used and the jack was NOT low profile. Maybe I can find the photo. The new

Get a longer hitch drawbar.

Many complain that they can not open the tailgate on their pickup while hitched to their trailer . Me too ! My jack is ten or eleven inches taller than needs to be ! Probably the same for most of you .

Simple, replace the standard jack with a "low profile" jack.

The big downside with low profile jacks is the range of height that they are able to lift, I have seen low profile jacks with as little as 14" lift.

If you have a Tractor Supply store handy, go and see what they have available that might not be as tall. Just be aware that the low profiles will often need extra blocking or a removable foot in order to get enough lift range.

Story is when Abe Lincoln was asked how long a man's legs should be "Long enough to reach the ground".
Look at your rig, side on. The tongue jack must extend far enough to reach the ground, plus enough to lift TV back up to the ride height when MT. Then it still needs to go down another 4 inches or so, to get the coupler clear of ball. Now unless you can get some help from Hermione, that shaft needs to go somewhere when you lift the foot off the ground.

The size of the jack head can interfere with the tailgate opening. I have a husky and no problem dropping the tailgate. Get a longer ball mount or turn the jack till two holes line up and drill the third hole.

The only reason I can think of is the screw jack has to have enough travel. About half of it is used, just getting from the up position to the ground, then you have to raise the trailer.
