Basically, the difference between the two is that the Dynamax has higher end fittings than the Forester. When we made our purchase, we looked at the two 2400R models and I just could not justify the difference in price based on fittings. Nice touches on the Iwata, like the ceiling and recessed LED lights, but there are known problems with the vinyl, padded ceiling splitting around the lights. Our 2400R has a CCC of 1138 pounds, more than enough for the two of us. In reality, all RV's today, seem to be a bit short on the quality aspect. There has also been a lot of complaints about the Isata dinette slide tearing / scouring the linoleum
floor and requiring replacement. We have been very pleased wit our Sunseeker MBS. I would suggest that you also consider the Nation series, as they make a nice unit and the interior is more European design looking that the others. Good luck,
