Adding tongue weight

My 30 foot Sunset Trail TT is a little light on the tongue weight -- about 200 pounds or so, I'd guess. My RAM 2500 has the 12K WD hitch with sway controller and the trailer porpoises on me. Not much but enough to notice.

Short of adding bricks to the limited storage area we have in the front of this RV, how do you go about adding weight so that you can increase the tongue weight?

Note: Already have two batteries and both 30 lbs. propane bottles are full.

Just a thought but are you sure it's a tongue weight issue. Usually a lack of tongue weight can cause sway but not necessarily porpoising. I would suspect age and quality of your trucks shocks might be the cause.

2016 truck and trailer. Truck has less than 4K miles and trailer has far less than that. Therefore, worn truck shocks are not an issue.

Have you actually weighed it? That looks like a 30 foot trailer that would weigh in the 6000 pound range. 10 - 15 % of that would mean a 600 - 700 pound tongue weight.

Trailer grosses about 10K so should be about 1K or so at the tongue. Closest scales is about an hour away so haven't gotten there yet.

Regardless of that, the original question is/was -- How do you add more weight to the tongue?

Yeah, your numbers are about what mine seems to be and what I would expect. The porpoising isn't unmanageable.

Was just chatting with another guy in the park here who has been towing TTs forever and he says he keeps this trailer just a bit nose low on the hitch. He also has a rear bathroom model with an outdoor kitchen (just like mine). He thinks that there's a little too much weight behind the rear axle with the outdoor fridge, large storage area in the bathroom, and a grey water tank back there.

I'll probably stop by the folks that installed my WH hitch this week and see if they think the ball should be dropped one notch.

Our trailers weight about 5700# dry plus stuff of about 1500#(yes,1500) so about 7200# ish. I also have 2-3 bikes out back so maybe that adds to porpoising and try to put chairs and other things on bed in front.
If you want to add weight to front , get a bracket to put spare under tongue. some trailers do this.
Google 4'-2x4 and pipe and bathroom scale to weight tongue .You can weight right at home.

I had a 30' TT years ago with the same issue. The dealer welded steel plates (about 36" X 6" X1/4" THICK) to the inside of the front frame. I think he added about 6 plates to get me more tongue weight. That stopped my bouncing issues.

Wow , now that is an old trick for a trailer that had a strong frame and suspension. would not be smart now with these "light weight frames"
Another thing I do is keep my can goods in the pantry while camping but put the box of cans next to the bed along with cooler of bevies there too.
