How Long of a Travel Trailer Should I Pull with Tahoe?

I read that for pulling travel trailers length is important. A general guideline I came across suggested that you could pull a trailer approximately twenty feet long as long as your vehicle has a wheelbase of at least 110 inches. If you want to get a longer trailer, it recommended that you have at least four inches of wheelbase for each additional foot of trailer length? I ask because I am currently looking at a 2021 Tahoe (120.9 wheelbase & 8400 lb. towing capacity) to pull either a Rockwood Mini Lite 2104S (22'4") or a 2507S (25'11"). If I follow this guideline, the Tahoe would be best suited for 22.7' trailer thus the 2104S would be the choice. Does anyone have experience or thoughts regarding pulling either of these trailers with a Tahoe or similar SUV?

I wouldn't hesitate to tow either trailer (assuming payload and capacity are good) with the Tahoe. Obviously I would be using a good WDH with integrated sway

If that formula was accurate, a dodge long bed crew cab 3500 would be limited to a 34.5' trailer. Formula is a more of a guideline, and not even sure I agree with it.

Different states have different rules for overall length of from 55ft to longer.


Length is from car front bumper to last piece of trailer.


Not sure its enforced much on interstates , but,,,,,

Do you mind telling us where you located these general guidelines?
I've always been leery of capability guidelines which focus on trailer length. Once a mechanic told me my particular truck shouldn't tow a trailer over 13 feet! What?

We pull a 25í TT with a 2019 Tahoe LS with max trailering package. We use a fast way e2 wdh with integrated sway control. We did have to purchase a shank with more drop. The first picture is from the dealership set up, nose high. The second picture is with the shank with more drop (sold separately of course). We also upgraded to Goodyear Endurance tires since pictures were taken. Only slight sway experienced was going around 70-75 while trailer was empty coming home from dealership, (probably due to the nose high attitude and excessive speed) it was minimal enough that it corrected itself. I was at the time maintaining highway speeds while pulling a TT.

Here is the link to the info I found on travel trailer length and it's effect on towing. I found very little information on length out there as most info focus on weights.

We have a 2016 Tahoe 9without the max tow feature) and pull a Rockwood 2109S and a 10K Equalizer hitch with no difficulty. I can easily cruise at 65-anything faster and my fuel economy goes below 10 mpg. It is very comfortable.

I pull a 21' 2109s with a 2012 Yukon and a Equalizer hitch. I do have the towing package. No problem at all, but I don't think I would want anything longer. In my opinion the short wheel base shows up big time when backing up witth the trailer. Very quick responce.

Which Yukon, the Tahoe length one or the Suburban length one? There are two different sized Yukons.

Trailer Length

For about 9 years, I pulled a 28' Pioneer with my Eddie Bauer Explorer with absolutely no problems. It was 4 WD with a Ford's largest V8 engine available for the Explorer.

The 2020 Tahoe/Yukon (non extended version) had a 116" wheelbase and the new 2021 versions went up to 120.9". This extra 4.9" may make a slight improvement in towing.

We tow a 28Ft Salem 28RLDS with 2015 Tahoe LT with Max Trailer Pkg. When we purchased trailer new we set it up with our old Husky Centerline WDH and Fricton Sway Bar. Had a couple of White Knuckle trips in windy conditions. Purchased a used Hensley Arrow and set it with help from Hensley and have logged over 25,000 Miles across NA with no issues.

I'm surprised that no one is saying anything about the payload number........as in in real estate it's location, location, location it's payload, payload, payload when it involves towing

length

There are many factors that influence the maximum length trailer. Your personal comfort being one.I would look at your Tahoe door sticker for cargo capacity 1 st. That may move you one direction after figuring how much weight you plan to carry w/ passengers and camping stuff. I towed a 21'-4500 lb. trailer w/ friction bar. I was not happy w/ that set-up.The size trailer you are looking at, you need a WDH.I would add 500 lb to the TT manufacturer's dry weight-always understated. Your advertised tongue weight will go up also w/ battery, full propane and anything loaded into the trailer. My Tahoe, like most SUVs is set up w/ soft rear springs more for ride comfort than max towing. You might consider where you plan to camp and for how many days at a time also. Longer trailers usually have larger storage tanks. National parks and state parks will usually have more available sites the shorter the trailer

And you will find, weight is going to be the big factor in RVing, not the length!

The vehicle manufacturers don't have trailer length in their specs. Its cargo capacity, rear axle weight, gross vehicle weight, hitch weight and towing capacity limits you don't want to exceed. They assume you have the trailer properly loaded with the proper 10-12% of trailer weight on the hitch.

Most people find that they are limited first by payload capacity. You need to get the right trailer weight, empty weight plus what you are going to add, take 10-12% and that's where you start on cargo capacity. Add in people, pets, and equip. Don't underestimate what you will have in the trailer, the fresh, grey, and black water tanks will have a lot of weight if you travel with them full.

The trailer length impact on instability comes in when you don't meet the 10-12% and have the trailer back end loaded, or violate one of the listed specs.
