B17 roofs and "series"....

After reading a thread about "wavy roofs" on certain years (80s) Bigfoot 17s I have to think that there must have been a switch in the construction process sometime between the very start of production and 2005 (when the switch from the 1500 and 2500 series happened).

The reason for this is the roof on my 97 is super strong...I was up there again the other day and it feels like I could do a jig up there....and I'm 200lbs! It's real stiff under foot. As far from "wavy" as you can get.

This leads me to think that sometime between the late eighties and the early nineties there was a change at the factory....think of it from going from "no series" to the 1500 series trailers maybe....Does that make sense to anybody? If so I wonder what year it was that the switch happened.

If I'm right it would mean that there are THREE "series" of BF17 trailers....not just two....Waddya think?

the pictures are a cross section of the roof in my 97...bottom up, it shows the wet bath enclosure...space...the glued-on headliner...the thin plywood/styrofoam insulation...the fiberglass roof....putty....and the hatch frame

Looks sound! I have a 2001 17' and I'm hoping my construction is the same. I have the cold pkg. version.

yeah, I'm thinking...

looking at a bunch of pictures....there is a possibility that the switch from original to 1500 series happened at the same time as the bigger rockguards happened.....so we're probably looking for the guy that's got the oldest Bigfoot 17 WITH a large rockguard......

(all speculating here of course....just playing Sherlock Holmes kinda)

could the difference in the roof be just that thin layer of plywood (would have to have an 80s owner chime in)....or maybe just more FG? (the FG don't look all that thick on mine)

Well I would say that our roof is a little on the "wavy" side and it's a 1987. We have an original brochure for it and it just calls it a "B17". It evidently came in three models, the B17SW (SW for "Spiritwing"), the B17Del. (Del. for Deluxe) and the B17Std. (Std. for Standard). We think ours is the B17SW given the features it has, but it could just as easily be a B17Del. with options. The previous owners listed it as a deluxe model when they put it up for sale. Kinda hard to sort it out, but there's definitely no mention of "1500" in any of the original literature that came with our trailer. We think we're the third owner. so you may well be right Francois.

My 91 Deluxe roof is strong I've been on it a few times.

I've been on the roof of our 2003 1500 series and it seems strong enough to hold me (175lbs). I stay along the perimeter to be safe, and crawl on all fours.

Evergreen and Daniel...

thanks Evergreengirl....I did notice that the original B17 came in very different models...some with no shower/hot water

Daniel, I notice in your registry that your 91 has the big rock guard....supporting my theory about that being the point where "1500" started. Anybody have a 1990 with the bigger rock guard?

Both your trailers exteriors look real sharp with new graphics and all...mine looks a little rough...made a stab at removing the graphics on the rock guard...didn't go too well......thanks for the responses

Just playing Watson to your Sherlock.
Perhaps the 1500 designation for the 17 started when the larger Bigfoots changed molds and they lowered the belly band. From looking at photos on fgrv4sale this seems to have been sometime between 1991 and 1994. Not sure just guessin'.

well.... Watson

the lowered belly band thing happened sometime around 2005 (bankuptcy and reorganization) and was the change from 1500 to 2500 series (different molds, more insulation, dual pane windows, etc)

what we are "investigating"....is the possibility (and the date) that a change happened between the "no series and lots of options/models" to the "1500 series with one single standard of production"

it's kinda looking like that happened....just looking for the "when"
it's also looking like it happened at the same time larger rockguards (with gas shocks) made their appearance

B17 roofs

My 1993 17CB appears to have a transverse beam across from side to side about 1/4 from the front. The roof slopes slightly down forwards and backwards from it and the 13.5Kbtu Briskaire AC sits slightly tilted to the back and to the drivers side. When putting in a Dometic supposedly 'Hard Start Kit' into the AC, I did not notice any movement nor flexing of the roof at all. (The kit didn't help with the Honda 2000i starting the AC - I'll be trying another Supco kit!)
The roof itself is a bit wavy looking at it but it is pretty solid.

Mike the reason I put the 9200 Polar Cub in mine was to be able to use the Honda 2000.

That's true for the 17's. What I was hypothesizing was that the 1500 designation for the 17's came at the same time they changed the molds on the 19's and designated them as a new 2500 series. From a marketing standpoint if they were renaming the larger trailers they might have renamed the 17's at the same time. Just a thought.

19s ????

the BF19 is a seperate trailer altogether...with dual axles.....(see first photo) I don't think it ever was produced in the 1500 "era"...let alone 2500

the second pic is of a 17, with smaller rockgard....the mold is exactly the same as the later 1500s (with larger rockguards)....have a close look at the distinct shape at the front, below the bellyband (second and third pics)

then the difference between the "1500BF17" and the "2500BF17.5"...fourth pic


so my theory is that at about the same time as the larger rockguard made it's appearance (1500series and badging) there was a change in the building procedures at the factory....no more options packages (standardized production of the 17s) and possibly a stronger roof structure...

just shootin' the breeze here.....still looking for the oldest B17 with larger rockguard....so far it's a 1991 model year...

I'm not sure what the distinction between the "large" and "small" gravel guards is, I can't tell from the photos although that "pointed" one on that B19 is certainly unique.

My 1989 B17G has shocks on the gravel guard. It also has a very strong roof as all of my 240 lbs. has been up there many times. It is mildly wavy but not distorted. It it's also peaked as Michael Pupeza describes in an above post.

I don't have a photo of the cross section but it's blue insulation foam sandwiched by fiberglass on top, and plywood underneath (interior ceiling).

Here's a shot of the front showing the gravel guard. So is this large or small?
