SP 36 vs GM 4106

[Tnr]

We are looking at a 1992 sp36 as compared to 4106. This may seem like an odd question but, from what I hear, the Wanderlodge.s (36) has a longer hang after the rear tires which tends towards a wider swing on turns and not as stable handling on the road and in wind where the 4106 at 35' seems to not have the same issues. Also is the 3208 Thursday with ZF tyranny enough power for that bus? We will be doing a lot of mountains. Thanks for the help.
