Heaviest Frame?

Sunnybrooks have heavy/strong frames - Venture Welding,I think. Our 2000 25' 5er had a 12" frame, our 98 31' 5er had 14" and our 2008 31' 8" 5er has a 16" frame. All boxed frames w/Dexter. Even when SB started building Lites in about 01 or 02 they kept the same frames as the Originals. They redesigned the Originals in 03 and the frames got heavier yet. Craig

I thought Jayco uses Lippert frames to there specs?

Who makes the frame for a 2008 cougar 278rk.

We camp quite a bit, and almost every mile on our 5er has been towing tandem. Most of it with my 5000 pound boat behind. Not sure who made the frame on my SeaHawk, but I am very happy with how it has held up.

Lots of folks reporting double towing with their RV with a Lippert frame and have no issues.

I've double towed with a '80s/'90s Thor/Fleetwood and Skyline 5th wheel trailers after I checked the frame out myself.
They all had a heavy wall double stacked tube frames.

Some of the thin wall I beam frames have had issues such as bottom I beam flange bent/twisted/cracked in the suspension spring hanger areas without towing doubles.

Lippert builds them to the specs furnished to them by the RV Manufacturer..if the RV Company tells the supplier to build them with cheaper (weaker) tack welds instead of fully welded frames to save money...that's the way they are made.

Make sure to bring your creeper!

Keyword...'currently'

OP is looking for 1996-2004 vintage.
Lippert had problems 2000 plus

You're in the right part of the country. Look at Arctic Fox, or Nash.

I'm going to be looking at anything from a 1996-2004 5th wheel, bunkhouse model, 24'-26', slide optional. I'm going to set it up to pull doubles (3500 lb. boat).

I'd like to get some feedback on trailers with heavier frames/construction, vs. those with lighter frames/integrity problems. In other words, which are the well-built trailers on the used market? Thanks!

I pulled a 3500 lb boat on a Montana 2955RL with a 10" Lippert frame. I didn't have any problems, but some of those units fell apart by themselves back then, without a boat. Those were not good years for Lippert, and pre 2003 were even worse. Not a lot of bunkhouse options either.

Anything with a frame built by Young's or Leland

Anything NOT with a frame built by Lippert
