Question re Bigfoot Weight

I just talked to a dealer that has a '93 Bigfoot 17footer. He says the GVWR is only 1800, for a vehicle w/bathroom that theoretically sleeps 5. Is this possible? That seems astonishingly light. I questioned it, but he repeated the claim. Current feets of that size are 3500.

Thanks,

Kitty

Kitty ... the old joke is:

How do you know when an RV salesman is lying?

When his lips are moving!

Now, this isn't true of all RV salemen. Some I know are wonderful people.

But if I were you, I'd ask the salesman if he would tow the rig in question to a certified CAT weight scale and let you witness the results!

GVWR ....

Dang, I gotta do a better job of reading folk's posts.

Kitty, the saleman (and you) are talking about Gross Vehicle Weight ... meaning, that's the most the trailer can weigh, with all your "stuff" in it, including water, propane, etc.

The limiting "gross weight" factor is the axle.

Most axles have axle tags which state the weight limits.

Now, it's possible the trailer ... with or without your stuff inside ... ACTUALLY weighs much, much more ... but the official "GROSS VEHICLE WEIGHT RESTRICTION" is 1800 pds.

Meaning the trailer is overloaded and dangerous.

So, once again, I'd have the guy tow it to a certified CAT scale to weight the unit before I'd buy it.

I realize that I could overload a trailer and exceed the proper tow limit, but are you saying a trailer manufacturer would tag an empty trailer with a GVWR weight lower than is possible, given the GW of the axel? Or are you talking heavy retrofits?

I won't put down money on anything until I prove I can tow it, but I'm not planning a cross-border drive up to even see a vehicle if I know the weight listing is bogus.

Thanks,

Kitty

Now, this is not pointing any fingers at Bigfoot ... but at the RV industry in general.

They all used to play fast-and-loose with weights, and yes, often a rig was build, overweight for its axle, as the rig left the factory.

Kitty ... don't consider me an expert on the subject ... but as I understand it:

Dry weight -- what a rig weighs BEFORE the factory installs options such as a/c, awning.

Actual weight -- what the rig weighs AFTER all options are installed.

Travel weight --- what the rig weighs with all the options AND all your stuff, including water, propane, clothes, food stuffs, etc.

Gross Vehicle Weight (GVWR) -- the MAXIMUM the rig should weight, period, at any point, at any time. The most limiting factor of the GVWR is the axle rating.

The way I read Charles' post

:wave Kitty, I think what Charles is saying is that the RV dealer may be getting his 1800 lbs. figure from the GVWR rating on the axle tag. This wouldn't necessarily mean this trailer is over weight... but, given that we know the later models are MUCH heavier, it does make one skeptical (as you are).

Granted the '93 may have lighter materials in the cabinetry, a smaller refrigerator, holding tanks, etc., but 1800 lbs. still seems awfully low for the GVWR... and I agree merits a trip to a certified scale, as Charles suggested.

That's the only way to find out how much the trailer actually weighs.

So when you ask a salesman: "What does this trailer weigh?"

If he answers, "The GVWR is 1800 pounds."

He is not answering your question.

He is merely stating what the manufacturer says is the MAXIMUM the rig should weigh.

What the rig ACTUALLY weighs is still is question.

Until 1998, or so (don't quote me on the exact time frame, because I'm probably ... usually ... wrong) ...

Casita used to build its 13 and 16 footers on a 2200 pound axle.

Since the 17 footer's inception (95 or so), the 17 footer was on a 3500 pound axle.

Now, all models are built on 3500 pound axles.

Rick ... those are for NEW Bigfoots, right?

The GVWR is the same as the axle rating for the 17 footer, 3500 pounds.

Sounds like they probably did the same thing Casita did ... move everything up to a 3500 pound axle.

Kitty, the thing you need to find out is what Bigfoot was doing in '93. Call the factory! Or climb under the rig and try to find an axle tag.

But, still, none of this answers the question of WHAT DOES THIS RIG weigh.

That requires a trip to a scale.

Yup - those are 2003 specifications from the Bigfoot website. I just posted them for reference. It still amazes me that the 2003 weighs about 2600 and Mike T's 1998 only weighs around 1800.


I agree with you Charles - take it to a scale.

(I'm afraid to take mine though! :o )

USing Rick's figures:

GVWR (and axle rating) = 3500

Dry weight = 2615

3500 - 2615 = 885 pounds for options (not in standard build), propane, water, you and your stuff.

That's why I bought a 21 footer

I carry more than 885 pounds in beer alone.

:o :o :o :o

Awning, second propane bottle, and a/c are usually not part of standard build, so you can easily have a couple of hundreds pounds of options that you have to add to the "dry" weight.

885 - 200 pounds of options = 665 pounds

665 - 264 full water tank (33 gallons X 8 pounds) = 401 pounds (also have 48 pounds in water heater (6 gallons x 8), and what you add to black tank, so the remaining weight is even less).

401 - weight of occupants (you do math) = ?? pound left for food and clothes

Now, weight of occupants in a trailer isn't as important as weight of occupants inside a Class A motorhome, because you aren't going to be inside the rig when it's bouncing down the road.

But, when you and your family are inside the trailer, you are part of the total weight ... and yes, over time, that can overstress the axle.
