We're looking at large 5ers and these things are HEAVY. I know a 1 ton dually diesel will get them moving down the road and that's not what I'm worried about. I'm worried about getting the rig stopped if something bad happens and the trailer brakes don't work, especially on downhill grades.
I wish I could afford a Class 8 Volvo tractor conversion, but I just can't right now, so I'm starting to lean towards a used Medium Duty Truck such as a Chevy C4500 or C5500 series that's been set up for 5ers. (Class 8 used in good condition and ready to roll as a RV 5er hauler = $80k, Class 5/6 used = $35-45k from what I'm finding).
Is Medium Duty overkill or a good idea?
Also, any other suggestions on MDTs and which Diesel engine will last the longest in this category? I've been reading about different Diesel engines and some seem to be more problematic (Powerstroke) and some seem to be unstoppable workhorses (like the Isuzu/Duramax 7.8 or the International DT466).
Before I could give a sensible answer, just how heavy is the 5ver you are looking at? This past winter we were looking at a toy hauler version, very nicely equipped, but it EXCEEDED my 1 ton dually by about 3k pounds. In all reality, I'm certain the truck would have been up for it if I was just running around the flat grounds of Illinois, but we a about half timers and live in ours half the year while hauling from coast to coast - it just would not work.
We still have our TT and I still own my 1 ton dually because we can't make the MDT transition and I won't give up my travels or travel in a RV without the luxury we enjoy. Our existing TT actually offers us that where a lighter, but more basic 5ver would not.
I'm a power wheelchair user, my truck is converted for hauling me and the wheelchair. We bought the TT when I still was using a van to haul the TT. We really like our TT and apart from one very heavy TH we have not found a 5vr that would work for us.
I've never been up on top of my camper since I'm a wheelchair user, my wife gets that duty. What do I tell her to look for up there? I'm guessing there is some kind of vent cap or something there, does it come apart for inspection?
We do regularly treat the grey tank, but I haven't flushed it like we do the black tank. I'll do that as we leave this CG. (We are in a MS State CG that's not full hookups :( at the moment)
Our camper is three years old, would the toilet seal have degraded that quickly? I'll go to a camper supply in the morning and get one. That's a easy change that could be the problem.
As we arrived in Florida this winter and began to set up camp, I discovered a very, very strong septic odor in the trailer. We had just completed a 1100 mile haul and the smell was not there before we left. After airing the TT out there was no more problem and we continued our normal treatment, dump, club and treat cycle.
This week we departed for the next leg of our journey and when we stopped, the smell was back again. I now smell it in the bathroom if we leave the door closed up for any time. The toilet functions correctly, holds water in the drain seal, and to all visible evidence, there is no problem.
We never travel without the tanks being drained, there's nothing leaking under the TT. I'm totally confused. Does anybody have any suggestions for us.
