Why did you go with a 5th wheel?

I grew up trucking and semis were the most solid feeling of anything I ever drove. I had a mini van when we got our first rv - a hybrid which was within the caps of the van. Well, I pulled the hybrid home with my old 1975 dually rust bucket cuz the van didn't have a hitch yet and I knew in less than 1 mile that I screwed up big time. I knew that bumper thumper was going to be too much for that 87 grand voyager so I sold the mini van asap and got a 3/4t lwb chev van. That was a GOOD match but I still knew I had to get back to a 5er type so I got rid of the big van/hybrid after about 1 yr cuz even WD hitches are a PITA compared to a 5th wheel. Then I got a 96 1/2t dodge gasser and a very lightweight 5er. That was terrific and a dream to drive and hook-up but then we really got hooked on RVing and taking long trips and the 26 gal tank and 9-9.5 mpg didn't sucked. I traded the 96 for a 97 ctd LB 3/4t and went to 18-18.5 mpg pulling that same 5er. It's been the metaphorical slippery slide ever since. The next 10 yrs turned into bigger 5ers til we got a 5er that, didn't require it, but I want plenty of truck so I got the 03 ctd dually in 05 to pull the 30 RLFS. Now, we just got a 15k gvw 5er and the truck is maxxed again. As already stated, it's not require but I like plenty of truck and I know where there is a Peterbuilt crewcab 8.3 ctd/Allison, right down the road from me. The slippery slide saga continues - stay tuned! Craig
