Default GMC 5.3 with max trailer kit vs 6.2

I am in the market for a new truck GMC ... I have now 2012 6.2 1500 gmc and it tows it good at 55-65 mph from Bogalusa to Venice but I have 210000 miles on it now so I know itís time is near but new trucks now are so high I was looking at a 5.3 with max trailer package that dealer said would pull my boat with no problem and it would save me 5 grand vs the 6.2 engine my boat trailer and motors weigh about 8000 without gear thatís also 200 gals of gas .... so what are yíall thoughts

Not even comparable. For that much weight and distance, take a test drive in a 6.6L gas 2500. Much simpler engine than the MDS 6.2, and available in every trim. You will be horribly disappointed stepping back in power to a 5.3 from a 6.2.

If you are sticking with a half ton and don't want to pay the premium for a 6.2 equipped GM, I would go down the street and shop Ford 3.5EB trucks, and 5.7 Rams. Both have gobs more seat of the pants power than the anemic 5.3.

That dealer wants to sell you a truck. I agree with the comment above; no comparison.

I pulled a similar sized boat with two different 5.3 trucks and the shortcoming was the half ton truck chassis - 8K is really pushing it no matter what the manufacture rates it for. As much as I don't want it for every other reason the next truck will be a 3/4 ton.

OP, I had a 2012 Silverado with the 5.3 and towed my Robalo R240 with it. It sucked. My boat with it's custom fight fishing tower, full of gas, fresh water wash down, bait, ice, rods, etc. was around 9k pounds. I bought a 2019 GMC Denali with the 6.6 Duramax and there's absolutely no comparison in terms of power and towing comfort. I daily drive it and it's not a big deal. With that distance I would highly suggest you look at a 3/4 ton truck.

I tow a toy trailer in the CO mountains with a Yukon 5.3. Anemic is not even close, the tow kicks it's butt. If I were to buy another vehicle it would not be a 5.3.
Hard for me to buy a new truck when I only use it 3 months a year.

Buy at least a 2500 hd with at least the 6.0L or bigger... You will be very happy.....The 5.3L is not the engine for that load, you will be unhappy with it..

As everyone else says, get a 3/4 ton truck. If the 6.0 is still available, get it, or the new 6.6 litre gasser if your trying to save some $$$.

those axles look to be 3500lb axles? so making 7k total.

reason i say this, is i question the 8k weight of the boat. i have a similar cobia 244 and do not believe it is anywhere near that weight. cobia and robalo use to be the same at one point.

so if the 6.2 did ok the 5.3 is going to suck big time! and find a new salesman, he obviously doesn't know shit about towing!

Heh...unless he's buying a worktruck, the Ford EB with A/C is going to be about the same cost as a 2500 diesel.

I have had a few Denail XL's and the 6.2 is strong and towed my total weight of 7800lbs well. I have also had a the Yukon XL with the 5.3 and I would not personally enjoy towing your rig with that set up for sure.

Clearly you have no clue about diesel prices....3.5 xlt and stx ecoboosts can be had in high 30s and low 40s.... very rare to find and diesel less than 50

I took that post as a joke. That a/c really puts things over the edge these days. However, itís not impossible. I think thatís a topic for another discussion, though.

find a different dealer. Yours is incompetent.

a 5.3 is a dog. It would be fine if you were completely local at low speed. Road trips with that weight and a 5.3 will make you question life choices.

the 5.3 from 14 on is a completely different engine then the prior 5.3 I believe the max tow 5.3 is rated to 11k the 6.2 is rated 12k the max tow pkg also gets a larger rear and heavier springs enhanced cooling .I have an 18 gmc with the 5.3 8 spd 3.42 rear rated for 9200 i have towed 6k with no issue

I towed my 24 SH bayboat with a 3.5 Eco and 5.3 3.42 gears. Thats under 6000 pounds.

The 5.3 downshifted constantly on every overpass or hill.

The Eco stayed in 5th gear at 70 MPH on Cruise control from LA to N.C. 1000 miles.

The 5.3 wouldn't hold 70 at all. The Eco tows more like a Diesel.

Find you another 6.2.
