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
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,
