I assume since I will be towing a fishing boat with it I am not breaking our new rules....here is my post from TF, you guys hopefully can help me

OK Guys, need some help...I currently tow my boat with my Sequoia. It tows just fine but squats a little. I'd like to keep my Sequoia for a long time so I'm a little leary since I'm now on a trailer 100% of the time. Looking at buying a truck to tow my boat and a Sailfish 2660 WAC (which is a lot heavier than my boat). Looking used...used to have a Dodge Ram 2500 Diesel and LOVED it...

questions I guess are:
we may only tow 1000-2000 miles per year, maybe as much as 5000 miles depending on how many trips to NC we take, is there a huge benefit to buying diesel over gas for this little towing. When the truck is not towing it will get very little to no use.

Any recommendations on what to look for? I know very little about trucks and have not towed a boat 100% of the time in 5 years and then my Ram was way more truck than I needed for my boat...

Thanks
Mark
