"barmcd"......"dougrainer" brings up a good point. Only CERTAIN Monaco/Holiday Rambler models had the bad trailing arms. Monaco made their own proprietary chassis, called the Roadmaster chassis. The MAJORITY of the Roadmaster chassis were the RR8R with four airbags and four shocks in the front and four airbags and four shocks in the rear. Six in the rear if it had a tag axle. They made a less expensive model, which includes the Cayman, I can't recall the name of the sister unit, that had a R4R chassis. This meant it had two airbags and two shocks up front and two air bags and two shocks in the back. This was the ONLY chassis that had issues.
With all that said, the R4R chassis is a VERY rough riding chassis. They made an enhancement kit ($3500.00) to improve the ride, but many said it didn't help much. Our friends have a 37' Cayman that I changed the shocks to Koni's, adjusted the ride height and lowered the tire pressure and it still road rough. They also had trailering arms that broke on the freeway and destroyed the transmission.
So......Monaco made many levels of motor homes and they were all pretty good quality with the exception of the R4R chassis models. If it were me, I would skip anything that has an R4R chassis and look at the Knight, Diplomat, Camelot and above, which are all on the RR8R chassis.
