2020 Heritage Glen HL grey tank size(s)?

My daughter and SIL just purchased a 2020 Wildwood Heritage Glen Hyper Lyte 22RBHL (Forest River). According to the specs, it has 62gal grey capacity. However, there is actually 2 grey tanks, 1 for the kitchen, and 1 for the bath/shower. I'm assuming that the 62gal spec is the combined total, but would really like to know what size each one is. Anyone here with that knowledge?
  • Forrman, get a "turkey oil pump", uses D batts, and will pump out a blue jug in 2 or 3 mins!! Fairly cheap, easy to use!!

  • We just bought the same coach last week. Our dealer said there are two 32-gallon grey water tanks.

    Side note, did you guys figure out a way to add fresh water when you're dry camping? We bought our 22 RBHL without realizing we can't add water with our 6-gallon water bottles, like we did with our last two trailers.

    Good guess, but only a guess. BTW, while Forest River's website shows grey capacity of 64, their downloadable brochure lists it at 62. The black is 32; I suppose that it's possible (likely?) that they simply used 3 identical 32 gal tanks for all the waste needs, but again, it IS useful information to know for sure. Having the 2 dump outlets (rear black /grey, and front grey) separated by at least 10' is a really stupid design which will complicate and delay the dumping process. I guess we'll need to contact FR for the clarification on tank sizes.

    Sure wish they had bought a Winnebago; then they would be able to get tons of documentation on the entire trailer, from wiring diagrams, to plumbing diagrams, to complete parts lists. Oh well.:C

    Are your daughter and SIL concerned?
    I'm not sure what your point is, but knowing the capacities is certainly not a bad thing. The shower would likely be the highest volume user of grey water, and combined with the bathroom sink, it may be easy to fill that tank while boondocking, and with separate dump outlets at significantly different locations on the trailer, combining them while camped is not a realistic option.
