I have no loyalty to any brand of vehicle. It's not like they are paying me or giving me big discounts so whatever fits the bill when I want/need it...that's what I get. With that said...The only thing that comes close to making me a fan boy is our Mercedes. I have never come close to "loving" a car, but man I like driving this thing and can't see myself owning a different daily driver now.
For trucks, I've owned a Nissan (first truck). It was a POS...

I got back from desert Storm in '91 and needed a vehicle. They were selling them for $3500 new. Boom. Done. I drove the wheels off it. I got rid of it 9 years later with 300K on it. Other than routine maintenance, a few clutches and timing belts, it never gave me any problems. Then I got a Ford F150 4x4. LOVED it. Great truck, very comfortable, loved the color and it drove nice. I only had that 6 years because I needed a 3/4 ton to tow a bigger trailer. Then I got a POS Dodge 2500 diesel 4x4. The biggest POS ever built. Fucking hated everything about it except for the Cummins. The only reason I bought it was it was the only 3/4 ton that would fit in my garage due to my HOA. The Dodge did its job in being a tow beast but I always described it as the "Yugo" of trucks. After it hit 100K, shit just started falling apart and it was $1500 or more every time. With that said, I had it 14 years and when I got rid of it, was at 300K. I was so over it, I listed it for $10K...I didn't get one look at it. To me, that was fair. People commenting..."Something's wrong with this truck...why so low?" So...I took the add down. A week later I listed it for $20K. Everyone wanted to buy it then. Just fucking stupid. Got asking price. Then I bough my Chevy 2500HD diesel 4x4 LTZ. I really like it. First time I got everything and more I wanted my truck. It drives great, lots of power, comfortable. Then we moved to Havasu 6 months later and I only ever use it now to launch and recover my boat. It really just sits in the garage. I'll probably have it 20 plus years and sell it with under 50K on it.
Lastly, We bough a new Super C. It's built on a Ford F600 diesel 4x4 chassis. It's on a lift and mud tires. Thing is seriously a beast. Tons of power, drives almost like a car. It gets decent gas mileage for a moho (10-14 mpg). With that said, I'm not a fan of the cab layout and quality. Maybe that's just due to a "commercial" type, mass produced platform. This was not designed for luxury or comfort, but for a work truck. It still has the Ford entertain package and isn't "bad", just nowhere near what my Chevy is.
With all that said and in my less than valuable opinion, I'd probably go with a Ford F450 if I was looking for more power/beef for towing. The one thing I can say about Ford, they don't take government money to bail them out and always come back strong. They are a good truck and plan on building trucks a long time. I have heard "rumors" that chevy might reduce their truck line. Not sure why, but I can never see Ford doing that.
