We like the KW. Pete and KW are clearly the most durable of the class 7's. You give a little in space but you can't beat KW service.
When you look at the resale end, KW and Pete bring alot more than their competitors. The only other class 7 truck that uses some class 8 components is Sterling. You can go to a class 8 but they will be more expensive. We have a ICT sleeper. They build them in the size you are looking for. When shopping be careful not to cut too many corners here. ICT, Bentz, Double Eagle, ARI are the better sleepers when comparing price and quality. If your budget is limited the above may have some used or reconditioned ones.
