Extending Camper Tounge?

The tongue weight that you are considering is not much TW. Either extend the trailer portion of the hitch or add an extension to the MH.
Been there , have done it both ways. Have no preference of one or the other. I did it with a lot more weight that you are talking about.
Many TC guys have to use hitch extensions bc of the rear overhang of the truck camper over the pickup.

hitch extension thread

I think we might need a little bit of clarification. You're posting in the Class C motorhome forum, you mention a pickup, and taking a "camper". When I see "camper" I think a slide in camper that goes on a pickup. Do you have a motorhome? If so, just use a hitch extension. That little boat doesn't weigh enough to make any difference. If you were towing something heavy you'd want to rethink that. No need to cut the RV frame. Or are you going to carry the boat on the back of the RV? Or are you towing a trailer with the boat in the back of your truck?

My post might have added to the confusion. I referred to TC towing with extensions was for extension info only. The link is from the TC section , regarding hitch ext’s.
Im under the impression that the OP is now using his MH to tow his boat bc he needs more room bringing his child on fishing trips.

I think I may have messed up and posted this in the wrong section. I'm a newbie with RV'ing so please excuse me if so!

My camper is a tow behind camper (Riverside Retro) and my towing vehicle is a F-150 SuperCrew. My boat is a small 10' bass boat that I slide in the bed of the truck.

My camper has a dry weight of about 2500 lbs. I'm worried about adding "Hitch Extensions" due to them compromising my hitch tounge weight capacity. With that said, instead of extending the hitch and putting more pressure on the tounge, I was considering extending the front trailer hitch by a few feet using some square tubing or C-Channel. (I have a 240v stick welder.)

OK, now it makes sense. A TT behind a pick up. I would build a bolt on extension that fits alongside the tongue U bolting to the existing frame and into the 2" hitch reciever of the trailer extending as much forward as you need. No need to cut the TT frame just make an adaptor for length. Got one for my 20' flat bed that allows me to carry 24' steel pipe and tube with out overhang.

Why not use a headache rack for the TV?

Moved from Class C.

Michael,
For a TT so light ,material shouldnt be more than the existing U bolted to the trailer frame near to the body of the camper , then going forward as long as you need with a X member with a hitch ball 2" ? that goes into your existing trailer tongue hitch to your new hitch
Add a ' lock over mechanism ' that prevents involuntary unhook at the original hitch. Then just make up a wiring extension . Lenghening the TONGUE ( proper spelling ) will decrease tongue weight with no ill but a positive effect as it shifts hitch to axle farther behind.
Towing and parking will be different , as you will need more turning room like a 5th wl rig does. because the axles are moved farther behind.
You write You have a stick welder. I take that as you are a handy guy, so can figure out the rest.

Ladder rack for the boat, no other modifications needed. We put a Pelican on the rack of a Suburban for years. 3 hp outboard inside.

Not exactly. The difference in how far a 5th wheel tracks inside, compared to bumper pull has everything to do with distance between rear axle and hitch pivot. As the front of TV starts to turn the tail swing moves the nose of trailer toward outside of turn. 5th wheel, must take wider arc with TV because front of trailer does not follow TV tail swing.
Now the extra distance between hitch pivot and axles will mean you need more room to maneuver, but normally makes it easier. The issue I see is extending the tongue will reduce TW which is likely to cause sway issues.
A rack that will let boat extend over cab while towing is likely a better idea. Also let you have bed for other toys/gear. Camp set up, take boat down off rack, load in bed for quick launch.
