A 2500 Ram 6.4 hemi vs a F150 with the max payload is apples vs oranges.
The 6.4 hemi 2500 Ram crew cab has a 5500 FAWR and full floater 6500 RAWR with a 10000 GVWR with payloads from 3030 to 3600 lbs.
The 3.5 EB F150 Ford super crew has a small 3750 FAWR and semi float 4800 RAWR with the 7850 GVWR with up to a 2900 lb payload.
A point about the F150 GVWR high payload numbers.
There is no F150 that can carry 2900 lbs in the bed as its a GVWR payload meaning the 2900 lbs is spread over 3750 FAWR and 4800 RAWR.
What truck the OP wants/needs is up to him. One will be a gazz hog as a DD but will handle that size trailer with ease.
The other will get much better mpg as a daily driver and it will also tow the 7k trailer with ease.
