They have gotten good comments. That vintage HWH slide is hydraulic and there have been some issues with the hydraulics.

Brett, other than a minor adjustment…ours has been flawless. Plus, when we do have to re-seal it will be less than 9000. Geo.

Example… A 2003 Marathon H, like others, have HWH hydraulic slides and the air seal. To replace the air seal, the entire slide has to be removed, not to mention the possibility of a hydraulic leak or problem. A Featherlite of the same year also has the HWH hydraulic slides, but may not have the air seal. Featherlite owners can verify that.

So do your homework to determine what you’re comfortable with.

Our friend has an HWH slide on their 2000 Featherlite, and it does not have air seals. He had an issue with the slide not working, and it turned out to be the electric motor powering the hydraulic pump. Being handy, he removed the motor and took it to a motor repair shop in Ft Worth. They found a bad ground, repaired it (for about $15), and he reinstalled the motor. Works like a charm since.

Vantare used what’s called a D seal…no air. Geo.

D Seal, or Bulb Seal is the same thing my Eagle has.

Will have to do some more checking, didn’know HWH made a slide with an air seal.

thanks again to all for info.

HWH Slide in the vintage you are speaking of (2000) is questionable. We had a 2002 Foretravel with an HWH slide. It had the bladder but more so, the “computer” that controls everything was prone to failure. I spent better part of a year working with HWH and the only fix was to send a complete controller, with all of the boxes (Front Slide, Rear slide). I installed the new controller and had fewer problems but not 100% solved.

My comment is I will only own a bus with Prevost slides.

We had 3 RVs with HWH slides one with 4 slides and 2 with 2 slides… the last one with HWH slides was our 1998 Vantare H3-45 and we did have a problem with the rear slide and after having the right folks working on it … it was fixed promptly… we had all the seals replaced very easily and inexpensively… I would recomend them… My understanding is that we had the first H3-45 with slides… Vantare installed them and they were great.

Hope this helps you.

Cheers, Diane

We are on our second motorhome. Our previous 4 slide Dynasty had 3 HWH hydraulic slides and 1 electric. During the 7.5 yrs. that we owned it, they worked great. Once, the large ‘pivoting’ slide behind the driver in the living room got quirked somehow. I had to drive it to service with the slide out about 3-4 inches. Another time, I had a leak in the hydraulic hose at the motor under the steps that ran to the back passenger-side bedroom slide (that was a long hose replacement).

When we decided to build the Liberty, I only wanted Prevost slides and NO PIVOTING slides. Easy in, easy out. The Prevost electric slides are very smooth.

Safe travels,

Mark

My 2001 Vantare has double HWH slides (no air seal) and thay have been flawless.

I am on my 3rd Vantare with HWH slides, no air seals, and no problems at all. (knock on wood)

Good
to know Vantare didn’t have the air seal with HWH, I thought that was
the case.

Another
consideration with the HWH hydraulics is the fact the HWH lines and
fittings are proprietary. You cannot go to the local hydraulic shop
and get a hose and fitting. Years ago when I had my HWH slides on 3
different CC fiberglass coaches, you could get the fittings from HWH
and then you had to find someone with the swedge tool to crimp the
new seal. HWH eventually stopped selling the fittings and forced
repair facilities to purchase a replacement line. This was and still
is an expensive repair running a new line from the pump to the
slide.

Buyer
beware….
