Looking to Lease. Towing 4000# travel trailer. I see a lot of 2.7 and 3.5 v-6 in dealer inventory. Do these motors do a good job? Currently have an '03 4.6 v-8 with 230K on her. It tows, but she's working. Thanks

 

At 4K either of those engines will out tow the 4.3. Just make sure you get a higher rear end gearing.

 

higher numerically to be exact.

 

At 4,000 your issue isn't the ability to tow but rather the ability to stop. You want to make sure your truck has a seven pin connector and trailer brake control. Assuming you don't want to start modding a lease truck.

 

Towing a 4000# trailer always turns into a 6000# trailer and gear in truck. Pay attention to payload. If indeed 4000# loaded, either engine. I do like my 3.5, maxtow, especially like the 36g gas tank.

 

Here ya go: Mixed opinions.

 

Either of those engines will tow circles around your 4.6.

 

2.7L, 4,500# trailer fully loaded. I've had it on a scale. No problem whatsoever. Doesn't even get hot climbing the mountain passes.
