Thanks all!
I just went to a truck stop to weigh my truck. My GVW without my dog (55lb) was 4,920lb, so with my dog in it, it will be 4,975lb. Now, GVWR is 5,400lb, so my max hitch weight is 425lb.
This is with full tank of gas and one passenger (he is 270lb). I know it will add another 270lb to the max weight if he is not in there, but I'm just going to keep it this way because this is really a possible situation.
So here's another question. Let's say I get an R-Pod 172. Dry weight 2,128lb/hitch 244lb. It probably is going to be 3100lb/380lb-ish loaded with options/cargo/propane/bettery (just guessing here). Do I want to add a 100lb WDH? It is going to be way over my capacity of 425lb (or GVWR of 5,400lb), but I know it is going to distribute some weight to the trailer. I just think it still is going to be heavier than not having an WDH. I am still trying to figure out how it works.... any input is appreciated.
I am going to look at the actual units they have at some RV places to ask the actual weight this weekend.
Thanks,
Jiro
