Towing question

Hi all,
Purchased a new 20' travel trailer which is a dual axle. I currently tow a large pop up with slideout that has electric brakes and single axle. So i have the round 7 pin connector on vehicle. I would like to tow the new trailer home but unsure if i can do it or not. I have to check if my current brake controller will work with two axles. If it does though, is there a different wiring to the trailer or will it still be a 7 pin connector. I am good on the hitch size but just unsure on the brake wiring. Thx

Most if all controllers will handle up to 2 axles. You may also want to check and see if the trailer actually has 4 sets of brakes. If you do have to change controllers, the wiring to the controller under the dash is the same. Most Travel trailers have a 7 pin plug so you should be good to go.

I've never seen a brake controller rated for only a single axle. The controller doesn't know if there is a single or dual axle trailer connected. The only difference is the dual axle will pull about twice as much current as the single axle; not a problem with standard brake controllers.

FYI, for a while, there were controllers rated strictly for a single axle but that was a LONG time ago. As I mentioned his controller is probably rated for at least 2 axles.

Thx all, purchased my controller new about 3 years ago. I will check but sounds like it will handle two axles.

I bought an el-cheapo DrawTite Activator 2 way back in 1999 - 20 years ago. It would handle up to two axles. So I'll bet that any brake controller you bought only 3 years ago, will work just fine on a tandem-axle travel trailer.

But just for grins, look up your brake controller on etrailer.com. Here's my old Activator 2 that's still available.

This is going to sound obvious, but most popups use a 2" hitch ball, while most TTs are 2 5/16. Make sure the hitch ball is the correct size for your new TT.
