Awesome - trailer project envy over here, thanks for sharing.
My $.02 - your adjustable tongue needs one more square tube attached to the frame further back (under the box). Currently, the fully extended tongue (as shown above) places all torque/moment at the bolted attachment (where you replaced the pintle). Adding one more square tube to the frame (with a longer tongue than what you've currently got) makes a big difference in terms of spreading load and resisting any bending or twisting over time.
So, longer tongue and one more square tube as an additional fixed receiver/support (new one being just a structural housing, no more pins for adjusting). Hoping that makes sense....
Good luck bud, looking good!
tlin, you make a good point here
though it might seem sound the leverage supplied by the extended tongue WILL apply extreme forces to the bolted connection thus creating the possibility of shearing the bolts making the connection
i'm seeing several long tongued trailers and up 'til now have refrained to comment
many of them are made of lighter tubing than i would have used
and they are unstayed underneath
anchoring a lengthened tongue farther back under the body will help a lot
if the tongue tubing proves too light reinforcement underneath will be necessary
MNJK10, GOOD LUCK WITH YOUR BUILD
