So im getting my first car and want something that i can pull a boat (fx21) and be able to throw some poles in so me and my buddies can pond hop that isn't expensive. Something that is sparing on gas mileage as well! I'm afraid a v6 might not have enough power to pull a 21 foot boat up a ramp unless its a bigger v6, but a v8 won't do as well on gas mileage. any ideas guys?

Get yourself an old Jag X-J6 with a moon roof so your poles stick out the top of the roof...

It will be a truck or full-size SUV. The right v-6 will be ok, but an 8 would be better.

The new Ford Eco-Boost V6 will do the job as will the new Ram diesel.

Do yourself a big favor. A Skeeter FX21 will weigh right at 4,000# on the trailer with all the junk we fishermen cram into one. Don't try to pull it with a small SUV. You need a full sized SUV or Pickup.

Wait for the new Colorado Duramax next year... have your cake and eat it too! $35k or so may or may not be cheap to you... but it's an elegant solution to thirsty v8's that keeps all the power you need to tow and ability to haul gear just as well as passengers and get around 30mpg.

Ecoboost. I love mine. Pulls a 21i class without a problem and gets decent mileage everywhere else.

Dang. I wish my first car was a new truck that would pull my fx 21.

I don't know about car but I bought a 2015 Nissan Frontier (Desert Runner Edition) earlier this year. 4.0L V6, 6,000 lb towing capacity. Cost was around $28,000. It pulls our 21 ft. travel trailer (~4,000 lbs. loaded) fairly well. I'm sure it would pull a good sized bass boat as well.
As far as yanking a big boat out of the water, I would opt for 4WD in a vehicle that size if you want to go that route. My little boat is aluminum and only weighs about 1,200 lbs., trailer included. My Fronty pulls it like it's not even there.

I'm afraid pulling a 21 foot bass boat and good gas mileage don't mix unless you pay the ultra premium for the diesel like already mentioned. When I bought my wife's 1/2 ton Dodge last year, I looked at the Ram 1/2 ton diesel. I didn't want to spend the extra money on the diesel, so we got the HEMI. It gets 17-19 driving around Texarkana and 21-23 at 65 down the highway.

My Avalanche does like 14-15mpg city and highway combined, and roughly 11mpg towing 2-2.5klb or so... I can't WAIT to get my hands on the Colorado Duramax lol

I'm thinking there are going to be a lot of horror stories about the small diesel trucks. Sure you can pull that 21 foot boat, but have fun stopping it if you get into a sticky situation or bad weather.

My first truck was a 1972 Ford F150 with a strait 6 and a 3 on the tree.

Speaking from experience towing a lot of miles I'd over kill and get something in a pickup that is 1/2 ton with a high towing capacity like a Toyota Tundra or a 3/4 ton of which ever brand you prefer, either gasoline or diesel. I've seen a lot of vehicles fold under the pressure, especially in this Texas heat. A few transmissions and a few motors have let go on me while towing a bass boat over the years. Most of the vehicles were 1/2 ton pick ups rated for around 6500 lbs. of towing. Even at that rating 2 tons of boat is just sometimes to much over the long haul and Texas summer weather. I'd go out and find something with at least 10,000 lbs. of capability so your tow vehicle has more breathing room.......

What $$ range budget do you have for this inexpensive fuel-efficient 21'glass boat hauling tow vehicle??

anywhere south of $25k your best option is to get a used 1/2 to 3/4 ton pickup and have your buddies chip in for gas money if they want to go fishing.

That's just ignorant talk... a modern "compact" pickup truck casts about the same size shadow as a modern "full size" truck. The difference is not that large, about half a foot in width. And any modern "compact" truck probably has about 10x the safety and strength of most 20yr+ old half tons.

You are fooling yourself if you believe elsewise. If you have a 90's "full size" and feel big, go pull p to the new dealer of your choosing and line it up next to their top trim "compact" truck and see how you measure up. The Colorado Duramax is going to be an absolute monster of a truck. Also worth bearing in mind most of my diesel truck driving buddies with full sized diesels run high 10's in the 1/4, and I am no stranger to building fast toys. The only thing a slightly lighter weight truck with the same size brakes and tires is going to do different than your full size truck towing the same rig is stop quicker, and accelerate faster. Only reason to have a heavier duty truck than that would be if you need to be able to handle 8,000lb+ payloads on a regular basis... and even my tremendously overweight old 20ft bass rig struggles to break 2500lb or so fully rigged, so I'll wager most people don't need more truck than that for bass fishing.
