We have a ’98 H3-45 with 2 slides… I understand that this was the first year for a slide in an H3-45… they were installed by the converters or for the converters I believe and were usually an HWH slide. We have 2 HWH slides and love them…maintenance is the key with your coach… we are still learning daily.
Our slides have been great we have only replaced the power switch on the rear slide… they work very well for us. When we had a levelling issue they wouldn’t lock… that took me an hour or so to figure out, then all was well again. I couldn’t enjoy a coach without slides … we went from a 4 slide plastic coach down to 2 slides without any problem, however.
If the slide is an HWH and works well I wouldn’t anticipate any problems, if it’s another brand I would check with someone who has one. I don’t think Prevost installed any slides in an H model unitl 2004 or later. HWH is the most used slide out there overall, so parts are not an issue.
As far as fiberglass issues, none that I’m aware of…
Good luck with your shopping … that’s the fun part.
Cheers,
Diane
