Having used both a 32 foot motorhome and 38 foot fifth wheel tou hauler at both Brodak and AMA HQ, I can tell you that both are good places to park...with reservations. At Brodak, one needs to arrive by Saturday afternoon to obtain a spot at the road. Toward the rear of the lot, should it rain, you may get stuck. Toward the street, pulling out is no problem even in the wettest weather. At AMA HQ. there are mostly electric spots, full 20 to 50 amp. There are 6 full hookups. Reservations are accepted. You can pull up to water to fill tanks and there is a dump site. At both places, if you have large tanks with proper water management you will have no problem with two people for a week plus. You can fill and dump at AMA but are on your own at Brodak.
