We started with a small class c (many yrs ago)Then went to a 29' class A this was a great unit for traveling and with twin beds it doubled well for a hunting cabin. Then we had a 29' TT that was our place on Lk. Erie for fishing. Then another Class A DP 35' this rig served us well for 10 yrs. and we travled all around the country over 100,000 miles. We decided that we we would not travel as long or as far and opted for a 35' TT. That worked well for a couple of years but when we decided that we had found our winter home destination we came across a park model at our winter site and bought it. We decided this summer that we really liked the convienience of the Class A and bought a 35' Newmar.
A 5er was never really an option for us because of the steps inside and out.
We have found the 35' length to be very good for us and fills our needs for traveling, getting in to most campgrounds, storage and roominess when set up not to mention the ease of setting up and tear down. We opted to go gas because of the price difference and the fact that we are not traveling the distance we once did. I have to say that at first I was quite disappointed in the handling of the F52 Chassis and spent nearly 2,000 on suspension upgrades. Now even though it is not the DP ride it is quite a good handling rig. We have a small home base home a park model trailer and the class A so we have quite a selection. If someone said now just choose 1 it would be a Class A DP. But so far I have all my playthings .
