That trailer will weigh approx. 7500lbs with a tongue weight near 1000lbs (12%). As long as it’s setup properly you should be OK. I towed a similar length TT with a 97 Dodge conv van. The trailer weighed 6500lbs. Your wheel base is longer than mine was.

If you come out West where the State flowers are wind farms, put a piece of coal between your cheeks and you may have a diamond when you get back home.

I towed a scaled 8300 lb 35ft Outback with a Chevy 1500 max tow 10 times a year for 6 years. Weight was never a problem but wind was. A couple trips I had to take secondary roads instead of the interstate. Ultimately it’s up to you and your set up. The hitch being dialed in is absolutely critical. Expect days when you won’t be able to relax. It’s certainly not for everyone. If you’re the type of person that gets nervous when your rig makes the slightest move then I would look for something smaller.


I'm similar. 8,200 lbs scaled (and GVW) and 34'4" length. I use a Equal-i-zer 4 pt hitch and spent a good chunk of time getting it set up. Biggest issue I have is porpoising on bad roads, Jasper to Banff or on the Oregon Coast. And no choice for secondary roads.

I'm good, but we are looking at bigger units so I'm looking at 1 ton trucks first.

Tow a 8k TT with overall length of 27' with 3500 SRW Ram diesel back and forth to Arizona. I would not want to do it with a 1500. Been in windy conditions and the 8500 lbs truck keeps it planted.

The only length restriction is the state max length of maybe 65 feet but does vary.

8000 GVWR trailer and trusting you have the exact truck properly equipped that gives 11,000 tow rating... drive safe, get a good hitch, and go have some fun.

That is longer than I’d tow with my half ton. In wind it won’t be fun.

At one time back in early 2000's on this forum, this rule of thumb ratio for WB to trailer length got mentioned a lot. I may be off a bit as I like it, but at the same time, disagree with it to be typed after ratio.

110" WB for up to 20' of trailer.
Per 1' additional trailer, 3" of WB
Not recommended to tow with a rig under 110" WB......

1, I call hogwash on no rig under 110" can tow. To me you deduct 1' per 3" like you add for WB.
This was also setup probably when station wagans and sedans were main tow rigs. Our stiffer spring trucks, shorter rear over hangs should be able to go a bit longer.vlike wise a typical 8 lug 25 longer than most 15 series. Sw 35 longer yet, same with a dually. Might be 2-4' per style of truck. You get the point. Like wise sine this was made for a ball mount, a 5w can and should be able to go longer IMHO about 5-6', as that is a typical ball over hang from the center of rear axle.

I know of a few other rules of thumb before the common GCWR ratings came out per say. I try to follow those more. And as far as GCWR / tow ratings go, I have no issue saying they again IMHO are a crock of shaving cream! Why, they are performance ratings. IE you can start on an X%grade, hold more than Y mph on a given freeway way grade not overheat etc.
If your like me, I pull grades 2-3x the current spec minimum. I've been on enough grades stalked out, buying new auto transmissions, burned out clutches due to too tall of hearing, not enough torque trying to start on 20+% grades.

My 8000lb loaded equipment trailer swayed to the point of almost taking my 12,000 lb empty dump truck off the road. WELL under tow rating etc. No hitch wieght! Improperly loaded.

I've been moved half a lane width getting hit with a 60-80 mph wind gust on I 205 crossing the columbia river, in my old K3500CC 8' bed pickup pulling a 6000 lb 25'TT.

Saw a picture this morning, of an 18 wheeler windward side wheels in the air, leeward side of truck and trailer resting on guard rails. After a gust Tuesday evening leaned it over on the Deception Pass bridge on north end of Whidbey Island. Good thing it did not go over the rail, or it is iirc a 200' drop, into 70ish feet of 6-8 knot current, 50F degree water. Or stationary water per say at high or low tide.

At the end of the day, it's up to you to decide if a given rig is correct one to tow a given trailer. If you want to pull an 8000 lb trailer, with a given chassis that has ratings to 12000, but you'd is rated to 6000.....depending on how your 6000 lb rated setup is geared, it might overall, do better than the one higher rated. I've out pulled a 1 ton dually 454 th500 with a 25 series 292 I6. With a muncie 4 so 4.10 gears at slow steep grades. Granted slower on freeways. But the 292 never got stalled out. The 454 equiped tig did.

Choose your poison correctly.

I HAVE to reply to this---first, anybody with the handle containing the words"61 chevy" has to be pretty cool.
Second, the remark from the Eastern Idaho fellow about coal between your cheeks funny! Thanks
Your set up is a little light IMHO. As I've stated here before, "a Toyota towed a space shuttle." I am wondering about some of the factory ratings being spewed with regard to towing.
Tire ratings, springs, brakes, etc-etc come into play. I'm not one to preach bigger is better, but safer is better. We have hundreds of trailer transports coming through our area (towing new units to dealers), and have never seen a 1/2 ton tow vehicle.
See you out there

Love this!!!!!

FWIW, I have the 5er in sig and towed it w/ a '15 F350 SRW, SB, 4x4, 6.7 and had no problems w/ it overall as 3700 pounds of it's 16,000 was on truck. Side winds really didn't pucker our lower lips much. HOWEVER, upon towing our 4 place V-nose enclosed snowmobile trailer w/ 3 sleds in it (about 30' +/- ball to tail) with no sway control hitch DID let the truck know it was behind it w/a stiff crosswind. Couple of times I had to get a better grip on wheel. And this is with 2 sleds in the nose and few hundred pounds of tube sand over trucks rear axle. Trailer is 2500 empty and each sled weighs about 400-500 pounds, max trailer weight is 7K, alum frame. So if it were me looking at the RV in question, I'd jump up to at min a 3/4 tonner.

. . . the length of the trailer has no affect on the tow vehicle . . .
Definitely disagree. A 33 ft. TT has a lot of real estate on each side. Acts like a big sail when there's high side winds. The only thing that counters that twisting/swaying motion brought on by high side winds is the sheer weight of the truck. The heavier the TV the more stability.

We've towed a few 30+ ft 8k-10k TT's with a 1/2-ton (5.5k weight) and 1-ton SRW truck (8.2k weight). The 1-ton SRW truck's almost 3k of additional weight brings a lot more stability to the table when there's high winds.

Lastly, even a trailer that only weighs 8k-10k could be handful for 1-ton SRW truck with a tow rating of 16k **IF** the side surface of the trailer is extremely high with high side winds. At some point excessive side surface area on a trailer can easily make the truck's tow rating completely moot.


Long TT can really affect the TV, in both side winds and with passing semis. It is the fact the pivot point on the TV is 3' to 4' aft of the TV's rear axle that will contribute to sway.
