otrfun is correct in his post, those are some odd #'s. I owned a 2006 wolf pack 30 wp , measured 35' overall length and towed like crap!! I pulled it with a 1995 ext cab long box f250 diesel. I changed the tires to 3 ply side walls rather than the standard 2 ply side walls and cranked the wd hitch 10 ways to sun and nothing and I mean nothing helped. I changed the wd to a 14k because I discovered this unit had 18% tw loaded with my 1800lb sand rail and I had to back it in so the 400 lb motor and 110lb trans along with rear of the rail were past the axles into the kitchen slightly. it did tow a little better empty than loaded but a 25 mph side wind would blow me into the next lane!!!! took 1 day to settle down once I got to the dunes from pulling that thing. I couldn't take it anymore and loved the pull through th'r and floor plan so I decided either I would get it figured out or convert it to gooseneck. I use go pro camera's on my rail so I strapped it underneath my truck to see what the susp was doing going down the road. when I was going straight is when I always felt the sway and through a curve the truck always felt tight and true. well I discovered the rear leaf springs were actually squatting under the load and this was giving me the sensation of sway. so I added air bags and re-built my front and rear sway bars and changed the front coils out to 1k lb heavier ones and added kyb mono max shock absorbers. did make the empty ride rougher but nothing that bothered me. I jacked the camper up and grabbed the wheels to make sure the hubs were snug, they were not, there was 1/8" to 3/16" play in and out per wheel. I got the tq spec on line and tq'd them. the leaf spring bushings got re-built at the same time because them were worn and I had it up anyways. all this helped greatly but still wasn't great so on my last trip back from the dunes I decided to take all our lawn chairs and cases of water and pop and my 3 tool boxes ( tool combined prob 500 lbs) and stacked them all up against the ramp gate. wow what a diff that made, tounge heavy in my case. never hauled water or fuel in tanks since the camp sites at the dunes have full hook ups.
I have a friend that bought a 2010 30 wp and hauled a rail and a bike down to the dunes too. his 2007 duramax 2500 crew long bed and equal 4 point hitch still had sway. on his return trip I told him to take the bike out of the truck box and put it behind the rail up against the ramp door. night and day diff for him too. still not a rock solid tow at interstate speeds though. I finally figured out the how to for interstate speeds, sold it and bought a 2011 295 wp fifth! now I could drive one handed at 75 mph! so I sold that truck and bought a 99 f350 dually quad long box 6 speed diesel and now I have to try and stay awake for the drive! lol also right off the bat, I added kyb mono max shocks, replaced the factory 8 ply tires and added 10 ply to be 20% over gvw ( so I could exceed 65 mph) and two 10 ply spares, dexter ezflex, bronze bushings with wet bolts and removed the reese solid fifth hitch and replaced it with and air ride hitch that dropped right into the rails in the bed of the truck. I can hang a coat on the hook and it's still there 2 state lines later. now that 06 30wp was rated as half ton towable by FR and my dying a$$ it was half ton towable! only way I could see that would be on a dead calm day on flat ground under 45 mph!! don't believe what the dealership says cause they are there to make money not figure out anything. camper manufacturers don't care either. you have to weigh you th'r and go from there and if your truck is rated for 10k lbs towing drop 10% and start there. just my opinion of course.
