If it were me, I would install an electric jack. I think that would maintain the structual integerity of the unit and be less expensive in the ling run.

ME TOO! Here's the recent discussion where folks helped me with this exact issue:
Electric Tongue Jack - Ever Installed One?

LeB...,
A well done tongue extension will be of benefit in several ways:
#1 The inherent original frame weak point can be corrected.
#2 The jack issue can be rectified.
#3 A longer tongue makes for easier backing.
#4 More stable mounting for tongue box.
#5 Room for propane bottle.

If not planned well, the tongue weight/ trailer weight ratio can be easily exceeded. The tongue weight should be between 10-15% of the trailer weight. Also keep in mind that the more weight on the tongue, the harder it becomes to roll around.
A good example is "Nuestra Casita" our 17' FD Casita. Due to many heavy mods including a 6" frame to axle lift, 24" tongue extension with propane fueled Yamaha 3000EUI generator in tongue box, dual propane bottles in cover, & extra battery in it's vinyl box she weighs 4000# and her tongue weighs 600#. A wheel on the jack would only work on concrete and I suspect it would not stop easily once she began moving. A certified welder did the tongue mods specifically for the reason that liability is on his shoulders if there are problems.
"Nuestra Casita" tows like a dream with our Toyota V8 Tundra with both WDH and sway control. The mods fit our desires for a, go-anywhere the 4WD Tundra will go, travel trailer. In "sunny" Southern California she has been subjected to 3" of rain in 30 minutes (no leaks), 75 MPH winds, 17- 110 degreeF temps, and since we went to bed last night, 2" of snow. She's seen lots more snow than that, but that is the most recent. We may well exceed 10,000 miles this year and have faith she'll do just fine.
Make your TT fit your needs, but just keep in mind to make changes safely.
See you on the road,
Kurt & Ann K.
PS, that crazy banana just won't keep the spring in his step!

If you have a power failure, what does one do to jack up the tongue? Or if the motor goes bad?

A better idea would to do a body lift and slide the frame out for reinforcement. For sure you would get a better welding job that way.
I would add a couple of things to what Loren said :

- If the tongue extension is significant (say more than a few inches), a reasonable rule of thumb would be that the extra strengthening added to the old frame should extend at least half the length from the joint to the axle.

- To reinforce the existing frame, it's going to need to have quite a bit of welding done on it within an inch of the floor of the trailer. Gulp.

Here's a link that might give you some ideas of the various jack options available.

http://www.northerntool.com/webapp/wcs/sto...Id=6970&Ntk=All

I switched from the factory top crank to a side crank jack when I installed a EU3000 genset on the tongue of our 16' Scamp (pics on the group website under Cindy & Al). Less than $40. NOTE: Before adding the generator, I called Scamp and asked if they thought I should strengthen the tongue due to the additional 150 lbs - the answer was 'No'

Most jacks I've seen can accommodate either a foot plate or a wheel - the above website lists these. You may even be able to swap the wheel on your swing up jack with the foot plate on the center mount (assuming thats what you have, I couldn't tell from the picture).

Oh, your storage box looks great. Do the gravel shield supports have lights on their ends? I feel another mod coming on.

Thanks Al, great information. My gravel shield supports DO have lights attached. See the pic below. They are $8 solar models which fit over the sheilds clasp.

This is just too cool! I purchased two solar lights for around the door area when camping....but didn't even think about doing something similar to this mount. I like it!

I think you put the stow box on the wrong end. You are going to damage the tv when you jack knife when backing up or u-turning. I just extended the tv tow ball 3 inches and my swing down jack has not damaged anything on the tv since.
Put the propane tank back with the battery where they belong. Just don't overload the stow box.
