Go with a Ford f150 ecoboost with the HD package or check out the new GMC 1500 if you want a 1/2 ton truck. The tow ratings on them are 11k , the f150 w/hd package comes with 2400lb payload and the GMC comes with a 1900 lb payload. I test drove the new gmc 1500 , interior is beautiful and the trucks drives amazing ! super smooth , quiet , feels solid , and huge upgrade in quality compared to other trucks.
But you should think about if you plan on upgrading to a bigger TT down the road or heavier one ? If thats the case then bite the bullet now .
