Looking at buying this TT...would love to know if any good or bad experience’s with this model.

Grand Design has a reputation for quality. However, it is not unusual to need a number of warranty repairs with any new RV purchase.

The 2670MK is a nice looking, but big travel trailer. I hope you are not thinking it can be towed with a half ton pickup or SUV.

Actually I am going to tow it with a 1/2 ton

OK. Check the yellow sticker (actually white with yellow markings) on the driver's door. The yellow sticker will tell you the payload (cargo) capacity of your specific truck. The payload is different for each truck depending on options. It will also tell the maximum towing capacity.

For half ton pickups the major limiting factor is the payload capacity. This TT has a gross weight (GVWR) of almost 8,500 lbs. That means it will have a tongue weight of a minimum 850 lbs plus 80 lbs for the weight distribution/sway control hitch. Thus, you will have used up 930 lbs of the max payload capacity. Then, when you add up the weight of passengers, pets, tools and other stuff, it's possible you'll exceed the cargo capacity of the pickup.

Then, there is the fact that this TT is over 32 feet long. So, in addition to the large frontal area wind resistance, you'll have a huge, high side that will act as a sail and get really pushed around by passing semis and mild crosswinds. Because of the large frontal and side areas, you should not tow over 80% of the truck's individual max tow rating.

Post the max payload and max tow capacity from the yellow sticker, and we can do the math on whether your specific pickup can safely tow such a large trailer.

Nice truck...big trailer.

Age-old question, can it pull it, probably, should it pull it? Well...

Do have one question, since you are in Oregon, near a couple of the nation's premier trailer manufacturers, have you considered a Northwood or Outdoors RV? Yes they are heavy, but if you choose wisely, you can get one that will be a decent match for your truck.

Example: Nash 26N

Now, it's not a flashy as the 2670MK, but it's tough, and well suited for your climate. (Of course we all have opinions, ha ha).

Which is one of the problems. The 2670 tongue weight is too low to start with. On the Grand Design owners forum many owners are having trouble with swaying. You need 12+% for tongue weight. The 2670 is a rear kitchen model and most of the weight goes behind the axles.

Most people add around 1000 lbs +/- for gear. Dry weights are usually low per the brochure. That TT will be around 7,000 lbs from the factory.
7,000 lbs = 8,000 lbs loaded needs a tongue weight of 960. That means you're going to have to load 300 lbs to the front of the TT. that will be tough because most the heavy stuff is at or behind the axles.

Checking your trucks door sticker will tell you how much cargo you'll be able to carry. Cargo is passengers, tongue weight and gear in the truck.

Quality wise they're no better or worse than others. Lots of Kool Aide drinking on the GD forum. E.g it doesn't matter how many problems owners have they still love their trailer.

We have the 2018 model of the MK2670. So far we like it. Towed it from Ohio to Maine last year.

Nice! I’m 99.9% that’s the trailer we are buying...been researching for over a year.

UVW is the unloaded vehicle weight which doesn't even include the weight of your propane tanks. Nor does it take into account any water in the tank or all your camping gear (pots, silverware, food, clothes, etc.) You need to know what the gross weight of the TT is which is called the gross vehicle weight rating (GVWR). *For the 2019 Grand Design 2670MK, the GVWR is 8,495 lbs. At a minimum 10% of GVWR, the tongue weight is 849 lbs.

And the yellow sticker on the driver's door says?

Why does these Nash/Northwood advertising pop up when the thread is about Grand Design?

Cumminsfan · 03-16-2019, 10:51 AM

Looks like the OP wants a larger TT. Lance doesn't make any near as big as the GD 2670.
Neither does Nash and any ORV that big is 100% a 3/4 ton towable.
To the OP have you considered the 2600RB?
Another thing to think about is that with the slides in on the 2670 there's no access to the fridge, sink or pantry. If it's not a concern then no biggie.
