So I just bought a 21ft toy hauler, its curb is 4800 and its max is 7800.. the 4x4 DC can tow 7100 lbs right? What about this tow hitch class? is it 3 or 5?

where can i take this thing to get weighed fully loaded? any tips on towing with these trucks I know they lag huh? I'm bummed

If it is a factory receiver it is a class 3 but it should be labeled/stamped somewhere. The class 3 receiver is capable of hauling more than our trucks, just make sure the actual hitch you slide in is up to the weight.
7100# sounds right but it will be a bit of work if you get off the flat area's.

One very important thing to remember when pulling a trailer is DO NOT EVER USE OVERDRIVE! Tundra does not get very good gas mileage while towing so always carry extra gas with you.
I towed one about the same size and I did not pass up many gas stations without stopping.
Everyone I know that has towed any trailer over 3 or 4 thousand pounds has not been very happy with the tundra
You can get it weighted at any truck stop or moveing company that has scales.

It's poss a class 3? That's a 5000 lb max right? My trailer is 4800 empty, with bikes, gas, misc it'll be close to 6500 but the trucks 7100 tow is rated when the truck is empty no gas people ect right? How about a tranny cooler weight dist bars and anything else? What am I looking at $$ wise.. I already got the tow pc

Sorry, Class iii/iv look the same but carry different loads.

Class III hitches are weight carrying (WC) and also are weight distributing (WD) hitches depending on the vehicle and hitch specifications. Not all Class III hitches are rated to be both. The hitch specifications will alert you to a hitch that is not weight distributing. Class III hitches used as weight carrying is rated up to 6000 lbs. gross trailer weight (GTW) with a maximum trailer tongue weight (TW) of 600 lbs. Hitches that are used for weight distributing are rated up to 10,000 lbs. gross trailer weight (GTW) with a maximum trailer tongue weight (TW) of 1000 lbs. The use of a ball mount and hitch ball of the same rating or higher is required. To use the weight distribution side of the hitch a weight distribution system is required. Class III hitches attach to the vehicle frame only. Always consult your owner's manual for vehicle rating.

Class IV hitches is very similar to Class III hitches except for the weight ratings. Class IV hitches are weight carrying (WC) and weight distributing (WD) hitches depending on the vehicle and hitch specifications. Not all Class IV hitches are rated to be both. The hitch specifications will alert you to a hitch that is not weight distributing. Class IV hitches used as weight carrying is rated up to 10,000 lbs. gross trailer weight (GTW) with a maximum trailer tongue weight (TW) of 1000 lbs. Hitches that are used for weight distributing are rated up to 14,000 lbs. gross trailer weight (GTW) with a maximum trailer tongue weight (TW) of 1400 lbs. The use of a ball mount and hitch ball of the same rating or higher is required for weight carrying. To use the weight distribution side of the hitch a weight distribution system is required. Class IV hitches attach to the vehicle frame only. Always consult your owner's manual for vehicle rating.
From Hidden Hitch, Class I Hidden Hitch Class II Hidden Hitch, Class III, IV and V Hidden Hitch trailer hitches, Autoglass Plus Newmarket, Autoglass Plus Bradford, Ontario.
Since the max tow rating for the truck series is over 7000# it would suggest a class 4 hitch.
That is what is listed on my sheet from Toyota.

Someone will tell you for sure but as far as I know,

4x4 is 6500lb GVWR
4x2 is 6800lb GVWR

I think you only get 7100lb with extended cab not double cab?

I believe the factory tow package includes a class IV hitch good for 10,000lb and 1000lb tongue weight.

Our Jayco ultra light has 4500lb GVWR and the tundra pulls it pretty well.
Keep the overdrive turned off and cruise about 60-62mph and we get about 11mpg average. I have seen 80mph no problem but you didnt hear that from me and it was only for a few miles......tires are only rated at 65mph.

I think you will be fine if you get it setup right its not so much the weight its the wind drag once you are up and rolling at speed the heavier trailer will probably handle better than mine we get blown around alot in the wind but it doesnt bother me so much I drive a set of double trailers grossing 80,000lbs between 120,000-130,000 miles per year.

Any truck stop or dump station will take care of getting the unit weighed just go when its quiet like early in the morning or late at night.

Good luck and happy camping.

if your truck is a 06, do not mess with the tranny unless you send it in to the dealership. Then ask them. I went to the dealership to buy a typical tranny filter and fluid for my 06 DC -- was shocked to find it is a "World Class" tranny. According to the guy, it is copmpletely sealed and requires a visit back for service at 100k miles, 75k if you tow a lot. Apparently they have to get it running, up to temperature, and slowly remove fluid from a certain port while they fill it at another port.

I don't know, I am sure someone here can clarify what I am saying. Bottom line is don't go buy a universal tranny cooler and just try to add a quart or two of fluid. It is a bit more involved than that.

The 2006 DC has a class 4 hitch. I would also get the 12x12 transmission cooler and install in series with the stock one.
