I've wantedto go RV'ing for years and now (actually late next Spring) is the time to take the bold step forward. My question revolves around the right truck for what I want to do. I had considered a Class A diesel pusher but that's just more than I really need. I've reconsiderd looking at a 24-32 ft. 5th wheeler or conventional trailer. Problem is with the truck to pull it with. I've now have a great 2006 Tacoma bought new and used only for recreational trips. I love it but it obviously doesn't have the beef for what I have in mind. Would the new 2011 Ford F-150 with the 6.2 liter V8 be strong enough for what I'm looking to tow? I can't really justify the purchase of a 250 series, diesel powered truck. A 250 series w/diesel is way too much truck for what it would be used for 90% of the time. Is a 150 class truck strong enough chassis-wise for pulling a trailer in mountainous areas and is a shorter bed OK for 5th wheel attachment? I live in Illinois but the vast majority of my travels take me to the the mountainous areas of the US. Power is important. The trailer would not be used for full-timing, not retired for a few more years and I'm single so I only need livable space for myself. Thanks for any advice anyone might have.
